Warm and toasty under foot

When thinking about how we heat our homes, an area that is often overlooked is the part of system that actually radiates the heat into the rooms. The higher the efficiency of the “heat emitters” the more money you’ll save on your energy bill – it’s all about flow temperature! It makes sense really when you think about it, the less heat the boiler needs to deliver the cheaper your bills become. It really is that simple.

Because Under Floor Heating (UFH) has a very low flow temperature, it keeps you warm and toasty under your toes without ever over heating you or the building. So, lower temperature needed, less cost to run the boiler – but still nice and warm!

How does Under Floor Heating (UFH) work?

We covered this in some detail on our website under the Products and Services section, however here is a useful summary:

Retro-fit floor

Example of a retro-fit floor

  • Plastic pipework, specifically designed for under floor heating, is laid in a sand and concrete screed (mainly for new builds or extensions) or over the top of an existing concrete/wood floor (this is called “retrofitting”)
  • Warm water from the boiler is pumped through the pipes allowing heat from the water to transfer into the screed or if retrofitted, emit heat evenly across the floor in your room.


Simply explained your floor becomes a giant storage of low temperature heat. By using the whole floor to heat the room allows the flow temperature of the boiler to run lower than conventional radiators and this increases efficiency.

What are the benefits?

In summary the benefits of having under floor heating in your home includes:

  • Low flow temperatures, which keeps the boiler running more efficiently
  • No radiators on show, which some people prefer
  • Suited to systems with weather compensation, working together to achieve more efficiency
  • Works well with other low flow temperature products like Ground source heat and Air source heat pumps
  • Provide an even distribution of heat, makes you feel warm
  • Very versatile, it can be fitted in both new builds and existing properties

The real key to saving money with an Under Floor Heating (UFH) system is in the design, layout, quality of controls and the attention to detail when installing it. Many claim to be under floor heating specialists, but at Clarity we believe you need to be a Heating Specialist – someone who understands the whole system and will achieve the best results for you and your home.

How hard water hampers heating
Hard water is a fact of life in Cambridgeshire and East Anglia. In fact, many residents will be all too familiar with its impact on their kettles. But when it affects boilers or heating systems, you can’t just grin and bear it. That’s because hard

A guide to header and expansion tanks
In the lofts of houses or business premises which are served by an older or traditionally designed heating system you’ll find two tanks. The smaller of the two is known as the header or expansion tank. These tanks can come in slightly different shapes and
