What is renewable energy

Renewable energy is generated from natural resources such as the sun, wind, and water, using technology which ensures that the energy stores are naturally replenished.  

What are the benefits of installing renewables?

There are lots of good reasons to use renewables. You will be:

  • making use of secure and local resources
  • reducing your dependence on non-renewable energy
  • helping to reduce the production of carbon dioxide and other greenhouse gases
  • creating new jobs in renewable energy industries
  • reducing your energy bills. In some cases you can generate income by selling your surplus energy back to your energy provider. 

How do I generate my own electricity? 

Solar panels and wind turbines

Our Underfloor Heating compnay - Warmfloor Solutions offer various technologies for generating your own electricity at home.

  • Solar panels
  • Wind turbines
  • Hydro

What is the energy costs for the Warmfloor Solutions products?






The Warmfloor Solutions Underfloor Heating products have long been accepted as an excellent means of heating both new or for the improvement of existing properties. The three basic solutions are: -


  • Easy Warm – Under tile Heating narrow profile mats
  • Heat Safe – Underfloor (either embedded in a concrete screed or contained under a wooden floor structure)
  • Comfy Floor – Insulated and heated floating floor system


All of these systems are essentially a continuous method of heating. Each of these systems provides the user with low capital cost, ease of installation and systems, which takes up little space.


Running Costs


The calculation of running cost at best can only be approximate. The actual cost will depend on a number of considerations:

  • User preferences
  • Temperature and switch on time set points
  • Insulation values of the properties
  • Cost of energy


With these variables in mind we can consider a number of average values in order to provide an idea of approximate costs:


As an example let’s look at under tile heating. Essentially this is normally used to take the chill of cold floor tiles and is not predominantly used to generate comfort conditions within a room. Under this presumption the heating system will normally be switched on/off as follows:


ON 6.30 am to 9.00 am  - 6.00pm to 11.30 pm

Total energised time period 8 hours

The cables will generally operate in an on / off mode controlled by the floor thermostat for 60% of the energised time period.


What is the energy costs for the Warmfloor Solutions products?


Additionally with the Warmfloor next generation Self Regulating Heating this provides additional energy savings by “turning down” the installed floor loading with it’s automatic energy adjusting feature within the overall energised period.


If electricity costs are 5p per Kilowatt-hour. Then for an installation based on 100 watts / m 2 then this equates to:


Energy cost = 8 x 60% x 80/1000 x 5  = 1.92p / m2 / day


Hours of Operation


The heating season in the UK is normally considered to be 230-days which is equivalent to 5,520 hours and over this period the average external temperature is 6.1 C. If, therefore, an installation is designed to maintain a room temperature of 21C against a minimum ambient of –5C then the calculated use per Kw of designed heat loss for continuous heating would be (21-6.1)/(21—5) x 5520 = 3163 hours. The actual hours of use are, however, appreciably reduced because of fortuitous heat gains from extraneous sources, i.e., solar gains, body heat, and heat from other sources of energy, electrical lightening etc. Previous building research has suggested that as much as 20% of heat requirements may be gained for “other” sources.


Individual applications / products will be assessed on a similar basis.

Warmfloor Solutions are pleased to provide additional advice and analysis.


Building Regulations 2001 – Part L


The latest revision to the Building Regulations Part L make significant changes to the 1995 version. The regulations have been divided into two sections, the first covering dwellings and the second with other types of building. The requirement relating to heating and hot water systems has been changed to include the whole system performance and not only controls as previous.


Compliance with Part L1 of the Building Regulations will have been demonstrated by one of three methods:


-Target U-value

-Carbon Index

Each imposes slightly different requirements on the space heating and hot water systems. The calculations can be complex. To support our customers in this assessment our partner company Rockwool Insulation (www.rockwool.co.uk) provide an excellent guide on the web site. You will note that Warmfloor Solutions appears on this site as a partner organisation.



Comparison with Hot Water based systems


When looking at comparison with other energy uses i.e. gas-fired boilers significant care should be taken since in addition to the variables above additional variables need to be considered: -


  •  Boiler efficiency
  •  Losses in the distribution of the hot water to the individual heated areas
  •  Controllability of the heating zones
