Introduction to Buteline

Buteline polymer tee & elbow fittings

Buteline fittings are integrally strong and durable, moulded from thermoplastic and pre-fitted with annealed aluminium sleeves.

These maintenance-free plumbing fittings fittings, once jointed with Buteline Polybutene-1 pipe, form a unique and technically superior joint. Users will find the total concept much quicker and more economical than other available systems. Buteline also have several innovative polymer alternatives to traditional brass fittings available, unique fittings that serve the same purpose (with some improvements in the case of the Bute-1) but allow for peace of mind and a potential cost-saving of up to 45%!Designed using hydraulic engineering concepts proven on high pressure hydraulic fitting-to-hose connections, Buteline fittings have an outstanding feature which enable them to overcome high stresses experienced in installation and while in service. The aluminium rings transfer all loads applied on the tail section to the strongest section of the fittings, thereby eliminating the risk of failure.

Buteline fittings are available in 4 sizes — 10mm, 16mm, 22mm and 28mm.

Fittings are technically superior, giving superb performance and durability over the long term with over 50 years of service life.

Main Advantages of Buteline Fittings

  • Lightweight, slim-line, one-piece design (no O rings or inserts), easy to use compared to bulky brass fittings
  • Post-clamp flare provides visual indication of joint completion
  • Able to provide metal-free contact with water supply, better hygiene, no leaching of harmful substances
  • Corrosion resistant, no scale build-up
  • Use is not geographically restricted by geothermal conditions or hard water regions
  • Easier to install, no time-wasting with bulky tools, sliding sleeves, brazing, or searching around for lost copper rings!

Tests are carried out in accordance with relevant national and international requirements. Equivalent hoop stress pressures for up to 14.7MPa and forces of up to 13,100N are used in determining the strength and resistance to pull out of assembled joints. Test temperatures range between 20°C and 95 ± 1°C.

 

The Technically Superior Joint… Explained

  1. 8mm WIDE FORGED CLAMP Minimum working stress applied (approx. 0.5 ton per sq. in.) allowing pipe material to “flow” into insert tail grooves.
  2. 2mm WIDE FLARE No stress from clamping transmitted to insert tail or pipe at end of fitting. End of metal sleeve cannot impinge into pipe, even in bending.
  3. TAPERED ENTRY, SMOOTH BORE Minimise resistance to water flow.
  4. METAL REINFORCING SLEEVE Guarantees no stress break in this critical area.
  5. FULL LENGTH ALUMINIUM SUPPORT Provides additional rigidity and resistance to pull-off. Seals against dirt and moisture.
  6. SEALING RIBS Narrow lands with wide grooves, ensure clamp stress is transferred into the pipe joint efficiently.

The New Light Weight Over-Lay Underfloor Heating Boards

The Disman Aqualay Underfloor System is easy to install.

Aqualay Master Panels are used to cover the majority of the floor area to be heated. Universal Panels are used as pipe
return ends and for areas with complex layouts allowing the pipe route to be positioned without compromise.
The panels can be fitted onto a wide range of substrates including concrete, screed, asphalt, chipboard and plywood. These panels are not designed to span across floor joists and must be fully supported by the floor which they are to cover. The panels
can be fixed using flexible cement based tile adhesive or low expansion PU Foam with screws and washers. The panels provide
an insulated floor surface with pre-set channels for pipe work.
When the water pipes have been fitted and tested, preparation of the Disman Aqualay surface for the final floor finishes can begin.

The Disman Aqualay Underfloor Heating System Solution is a high performance pipe carrier panel designed for use with Wet/water based systems.

The Disman Aqualay panels are produced with pre-set pipe channels set *100mm, and 150mm centres and comprise of 3 different panel options;
Disman Aqualay Master Panel
Disman Aqualay Universal Panel
Disman Aqualay Multiflow Panel

Each panel offers uniquel designed benefits that make Disman Aqualay a superlative system for underfloor heating.Disman Aqualay over-lay panels are designed to provide a durable overlay pipe routing system for use with low pressure water heating and cooling systems. Disman Aqualay provides benefits such as insulation against downward heat loss, heat transfer across pipework centres, improves warm up time to floor finishes and provides controlled spacing for pipe-work. The Disman Aqualay is available with pipe channel centres set at *100mm for 12mm diameter pipe and with 150mm centres for Disman underfloor heating pipe diameters of 12mm and 16mm.

Disman Aqualay Master Panels are manufactured using high density extruded XPS as its core element finished with a hard wearing cementitious surface. Running through the body of each Master Panel is a series of highly effective heat transfer cores, manufactured from a unique conducting cement compound designed to transfer heat from the water pipes to the panel surface. The patented Master Panel is unique in structure, providing insulation against downward heat loss whilst at the same time effectively transferring heat from the water pipe to the floor surface.

Disman Aqualay Universal Panels are manufactured using a lightweight polycement based compound as its core element. These panels provide installers and designers total flexibility for complex pipe route layouts. Disman Aqualay Universal Panels effectively transfer heat across the floor surface, however they don’t offer the same level of insulation as the Disman Aqualay Master Panel.

Disman Aqualay Multiflow Panels are manufactured using high density polystyrene with cement reinforced surfaces. The
eight channels of the Multiflow are designed to retain heat within the water pipe ensuring heated water is directed efficiently to the required heating zone.

A chat with Frank….. A life less hurried.

So, a few months ago I got chatting to a guy I know on Moulsham Street in Chelmsford. He’s a nice old guy, out walking his dog, I know him from the pub. Clearly eager for a chat, he started talking about something he knew I would respond to….. rugby. Probably the one of the few things that this charming, well to do guy and I have in common. So, we chatted for five or ten minutes about the changes in the game since he and I were playing (30 years for him, not so much for me), putting the rugby world to rights.

Anyway, while I was chatting to him, a guy stopped to read the details on the B-Hive Underfloor van. Ever the opportunist, I politely broke the conversation from my evergreen friend and asked if I could help this new guy. Tony, it turned out was re-furbishing a house in Chelmsford but couldn’t find the underfloor heating system that would work for him. So, yet again I started to chat to a guy on the street about something I find very easy to chat about.

Tony’s plan was to completely renovate a 19th century cottage. He was planning on getting as much insulation in as was practicable, replacing all the sash windows with reproductions, using the most efficient gas boiler he could find, whilst trying to maintain the character of the building….. “sounds expensive” I said.

Anyway, as the proportions of this cottage weren’t what he needed for his family, he wanted to do away with any unnecessary bulk in each of the rooms….. specifically radiators (his words). Underfloor heating, he said, was what he wanted.

In the space of about 10 minutes we’d established exactly what he’d use, gone through the pro’s and con’s of each system or solution available on the market, screed, floating, diffusion plates…. everything we could think of between us (he’d done his homework). By the end it seemed the best solution was one that met pretty much all of his needs.

Aligned with the Delta Dore home management control system, to help Tony monitor everything at home from his offices in London, we settled on a solid over-lay system board. Disman routed Fermacell panels laid directly onto the existing floor boards (new insulation below), and run with 12mm MLC pipe back to the centrally place Disman underfloor heating manifold under the stairs.

Raising the floor height by just 19mm, Tony decided that there was more than enough head height in his property and was happy to move forward with pricing and design. Furthermore, this system helped with his wife’s desire for ceramic floor finish, perfect for underfloor and laid directly onto the boards.

A few months latter the system’s in and working, Tony’s happy, his wife is happy, I’m happy and I think Frank, my old buddy on Moulsham Street was happy for the chat. I was in a rush that day…. work, family etc. all the pressures we all experience in day to day life, but I’m glad Frank stopped me. If he hadn’t I wouldn’t have got the sale. I won’t be rushing past him on the street next time….. and I must buy him a pint….or two.

How to calculate a bill of materials for an underfloor heating system

Too often in the past underfloor heating companies have shrouded the specification of underfloor heating systems in mystery. The fact is, it is pretty straight-forward to work out what exactly you would require if you follow these principles;

Firstly, there are a few questions we need to answer;

  1. What’s the floor construction? Screed, Joists, Overlay?
  2. New build or refurbishment? If it’s a refurbishment, how old is the property?
  3. What’s the heat source? Boiler, Heat Pump?
  4. Preferred Manifold position. This is not essential at pricing stage but can avoid confusion and any crossing of pipe on the installation.
  5. How many heating zones will be required?

Once we have these answers, in general, we can specify what materials will be required.

We’ll take a new build house as an example;

Block and beam construction, therefore generally a screed will be used. The building will be using a heat pump as a heat source, therefore we would suggest installing the pipe at 150mm centres to allow for lower running temperatures and a more efficient system (Where a gas boiler is being used this can be moved out to 200mm centres in account of higher supply temperatures available).

Next we need to decide how many heating zones are required. Single room systems are just that, a single zone, regardless of size (Exceptions in very large commercial or multi-use domestic rooms may apply). In a building with multiple rooms on the ground floor, for example a large house, more than one zone would be required. Living room, dining room, kitchen, hallway, WC etc. can all be monitored individually allowing for greater control and a more efficient use of energy.

Each zone should be measured in square metres. Once we have this we can calculate the amount of pipe required. At 150mm centres the calculation would be m2 x 7.5. Therefore a room of 20m2 would require 150 linear metres of pipe (this figure includes additional pipe to allow flow and return to the manifold). It is important to remember that when using 16mm multilayer pipe, any single loop on the system should not exceed 120 linear metres. In the case of the 20m2 room you would therefore require 2 ports on the manifold. This process should be repeated for each room within the building remembering that not all rooms will have a single port on the manifold.

Example Calculations

Sample-B-hive-ufh-calc-sheet pdf

 

Sample-B-hive-ufh-calc-sheet 2

Often we see that 2 areas in close proximity may have very little pipe required. In this case, the hallway and WC have just 67.5m combined. In cases such consider combining them on a single loop. Doing this will reduce the number of ports on the manifold and the number of thermostats required. Here we have highlighted this by blanking the WC in red.

Based on this information we can now begin to create our bill of materials. In this example, we will require 517.5 metres of pipe, a 6 port manifold and 4no. thermostats. This is the basis of the complete system. Everything else required can now be calculated.

Pipe Clipping

We would recommend at least 3no. ‘U’-Clips per linear metre of pipe if this is your preferred method of attaching the pipe to the insulation. If you prefer to use clip-rail we recommend using 1 linear more of clip-rail per square metre of floor area. Experienced installer may use a combination of the two for speed of installation and money saving.

Edge Insulation

To calculate the the amount of edge insulation required we recommend calculating as 1.1 linear metres of edge insulation per square metre of the project. In this case, circa 76m.

On the Manifold

Pump & Blend Valve.

As we have discussed, this example uses a heat pump as a heat source. In cases such as this it is often the case that a pump and blending valve is not required. Please check this before ordering.

Actuators

If you are specifying a system for a single room, actuators will not be required. However, once you move to multiform or multi zone underfloor heating systems, each port on the manifold will be required to control the flow of warm water. Each actuator will be connected, via the wiring centre, to the relevant room thermostat and out or close depending on the required room temperature and any time programme enabled.

In terms of the manifold itself, this should come complete with ball valve, fill and drain caps and pipe connectors. Please check that your supplier provides all of this as a kit. Do not assume this.

Temperature Controls

Thermostats

In this example we have assumed that the client would require 4no. thermostats as the hall and WC are going to be combined. There are a mass of options on the controls front available in the market. Anything from the traditional dial thermostat to the higher costs internet enabled intelligent systems. Each has their place in the market, just make sure that you or your client are capable of using the more advanced systems as some are more complicated than others.

Wiring Centres

You will require a wiring centre to control the multi-zone system. This is a central control point that communicates between the thermostat, actuator, pump (if required) and the heat source. Placed next to manifold, this controls the entire system.

Do I require an underfloor heating design?

Many, many people install underfloor heating just using their knowledge and a little common sense. We are a nation of DIYers after all. However, it is alway a good idea to get a design done, especially if you have little experience of underfloor heating or if the system is for multi-room dwellings. Things on site can get a little confused when you have to get the pipe to and from rooms some distance from the manifold. A design should also provide you with the exact length of pipe required, the flow rates and outputs of the system which all comes in very handy. In short, our answer is that you don’t need one but we’d advise you do. Your supplier should be able to provide the underfloor heating design.

Enough Ethics?

We love this little note direct from one of our favourite authors… Seth Godin

Enough ethics?

Most companies seek to be more profitable.

They seek to increase their Key Performance Indicators. More referrals, more satisfaction, more loyalty. They seek to increase their market share, their dividends, their stock price.

But ethics?

In fact, most companies strive to be just ethical enough. To get ethics to the point where no one is complaining, where poor ethics aren’t harming their KPIs.

What if instead…

Being more ethical was the most important KPI?

Perhaps profit and market share and the rest could merely be tools in service of the ability to make things better, to treat people ever more fairly, to do work that we’re more proud of each day.

It might be worth trying.

What’s the point to Point to Point Plumbing?

Long used on the continent as the standard, point to point plumbing is fast becoming a new build and refurbishment plumbing and heating systems solution in the UK market.

Essentially, the increased use of flexible plastic pipe work and the markets desire to improve installation times and reduce the possibility of leaks within ceiling, walls and floors, has lent itself to this type of installation.

The basic principle is that each outlet, appliance or radiator has a single flow and return from a centrally situated manifold. Whilst this means a large increase in the amount of pipe used in each installation, the use of fittings is no longer required (except at the manifold and point of use). The lack of fittings means less time on the installation, less likelihood of leaks, cost savings and ultimate systems control from a central point.

Each system can be isolated at source or, should the correct manifold be used, each outlet or appliance can be isolated for maintenance or repair whilst the rest of the system can remains in full use throughout.

Now, we appreciate that this kind of system would not be suitable for all installations but for those with the scope and vision to pre-plan for this type of installation, the benefits can be significant.

For further information about this type of system, its design, and the components available for installation, please feel free to give us a call on 01245 490 401, or see here…
