Q: Which Underfloor Heating is Best, Electric or Water?
A: Both underfloor heating systems achieve the same thing, 21 degrees is 21 degrees whether you use electric or water. As a rule of thumb warm water underfloor heating systems are cheaper to run over the long term, electric underfloor heating can be cheaper to install but costs more over the longer term. We generally recommend water systems wherever possible due to their more economical nature.
Q: How Much Does Underfloor Heating Cost to Run?
A: Water underfloor heating systems are typically 20 percent cheaper to run than a traditional radiator system powered by a Gas boiler. Electric underfloor heating systems are cheaper to run than Oil, LPG, and Electric storage heaters for those who are not on the gas network.
Q: What Floor Coverings Can I Have on Top of Underfloor Heating?
A: You can almost any type of floor covering over underfloor heating, this includes but not limited to: Amtico, Karndean, Marmoleum, Laminate, Engineered Wood, Carpet, Tiles and Stone.
Q: What’s the Maximum Thickness of Floor Covering?
A: Engineered woods no more than 22mm, Stone and Ceramic tiles have a good thermal transfer and we have installed underfloor heating under 50mm flags to good effect. Carpet and underlays need to have a combined tog value of 2.5T or less. (yes carpets have tog values!)
Q: Do I Need Floor Insulation?
A: Yes we strongly recommend the use of insulation otherwise you could have a heating system that is very un-economical to run. More insulation is better in this situation where floor heights permit.
Q: What is the Cost of Installing Underfloor Heating?
A: This one is hard to answer in general, the cost will depend on your project and the ease of installation. Most projects can be completed in one day and others take weeks such as large commercial installations. We look at each job on its own merits and listen to your needs, we can design a system that suits your property, we do not install systems that are not suitable for you or your property.
Q: What’s the Minimum Screed Thickness for Underfloor Heating?
A: By selecting the correct screed we can go low as 40mm screed. This is the minimum before the screed becomes weak, and the plus side you will save money in material cost and the underfloor heating system will heat up quicker.
Q: How Long Before I can use my Underfloor Heating after Screeding?
A: It all depends on the type of screed, but some systems can be turned on as soon as 2 days after installation, others can be 7 days longer.
Q: What’s the Drying Time for Floor Screed with Under Floor Heating?
A: Again this is entirely dependent on the type of screed used.
Q: Which Areas of the UK do you cover?
A: We cover all of the UK, but most of our work comes from Yorkshire and Lancashire, Midlands, North East and North West.
Q: What Happens if my Water Underfloor Heating Develops a Leak?
A: Assuming the leak is obvious we can easily locate the damaged section of the pipe and repair it.
Q: Should I Leave my Underfloor Heating on all-day?
A: We suggest leaving the system ticking over during the day and using the set-back feature on the thermostats overnight to keep the heat in the floor and to not allow the slab to go completely cold. For example, if your day time temperature is 21 degrees Celsius, we suggest allowing the system to cool down to 16 degrees, then in the morning the heating system hasn’t got to do a lot of work to come back up to 21 degrees.
Q: what Brand of Underfloor Heating do you Install?
A: We mainly supply and install Emmeti underfloor heating systems, but we have also fitted Polyplumb AKA Polypipe and JG Speedfit – we have used Nu-heat underfloor heating, Robbens underfloor heating is another one we use, also products from Underfloorheating1 at Doncaster, rehau – We prefer to use Emmeti but we are happy or quote you using your preferred system – we don’t normally supply and install products from Wickes underfloor heating or b&q underfloor heating, but screwfix do a half decent range.
Q: How Much Screed Is Required Over Underfloor Heating?
A: This depends on the type of screed – but if its a flowing screed then we can go as low as 40mm – the norm is 50mm and sand & cement screeds about 65-70mm.
Q: How much to install underfloor heating?
A: This questions is hard to answer – its based on each individual project, and no two jobs are ever the same, what we will do is promise to be as competitive as possible and the only way to find out the cost is to contact us using the form on the right or phone 01274 568 536
