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.

That is all.




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.

Power Flushing – what is it and is it needed?

We all know that underfloor heating is an incredibly efficient, beautiful-to-walk on way of heating that will keep the whole house evenly warm. But it’s not easy to fit after the house is built and if often added during a home refurbishment or when adding an extension on. This often means that a new underfloor system is ‘bolted-on’ to an existing heating system. Which is fine of course, and works really, really well when the system is correctly balanced after installation.

However, should you be concerned about any rust in the existing system? Well, if the old system has a LOT of rust or sludge in it then you might need to consider get a power flush done to avoid potential problems in the future. One other alternative is to have a filter installed on the flow pipework just before the manifold. But make sure you have access to it and remember to check it regularly. Not sure if your system needs a power flush? Don’t worry, your installer will advise you. Most plumber and heating engineers these days have their own power flushing equipment, but if yours does not then it would pay to go to a specialist power flushing firm like


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.


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


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.

August Featured Product – Flexigas Pipe & Fittings


In a new monthly “Featured Product” we will be looking a little deeper into the features and benefits of specific products within the B-Hive Supplies portfolio. Hopefully, this can help our prospective and existing clients further understand the technologies and better determine which products are right for them and their projects.

The inaugural featured product is our Flexigas semi-ridged gas pipe and fittings. New to the UK market in terms of it’s branding, this type of product has been a available here for a number of years now. Brands such as Gastite, Tracpipe and have made large movements to aid the installers and specifiers with flexible gas pipe and fittings. Enabling faster installation in both new build and refurbishment without the need for time consuming braised fittings, many installers use it as a matter of course.

Flexigas logoFlexigas7

During our research into the product before taking it on, our team discovered four main objections to the use of Flexible gas pipe;

1. Many installer insist on using the tried and tested, traditional copper installation simply because they have been doing it that way for years.

2. The specification of the project design simply says that copper is to be used on all gas pipework.

3. The Cost. Up until now the cost to the installer of Flexible gas pipe, as especially the associated fittings, has been prohibitive. Compared to the cost of copper, the capital costs versus time saving benefits just didn’t add up.

4. I can’t get hold of it. As the demand for this type of product increases more and more plumbers & builders merchants will stock the product but for the time being, many places have to order it in.

For those traditionalists insistent on using copper we can only spout the key features and benefits, something outside of our influence will be the only thing that changes their mind on that one. For the specifiers, a greater knowledge of the product, the better marketing of the product, the better sharing of the testing and technology will be the way forward for the manufacturers sales team.

Cost. We agree that the costs of the existing brands in the market has been too high for too long. Whilst Flexible gas pipe is a huge move forward in product technology, it should not be so expensive in the UK market. Flexigas is not expensive by comparison. Copper will always be the main competition but, put simply, Flexigas, when the capital costs versus time saving benefits are recognised by the specifiers and installers is in with a genuine shot.
