Hello there,

I am looking to have an electric underfloor heating system fitted on an uneven concrete floor for the whole of downstairs.

Downstairs comprises of a hallway, lounge and kitchen. I want to have two thermostats to regulate the temperature of the lounge and kitchen separately, the hallway would be controller by the thermostat in the lounge.

It has been recommended that I use a 160W system.

I have been trying to figure this out for a while but I can't quite figure out what order things need to be done and what products people would truly recommend which are reasonably priced and reliable.

So far I think that you cover the sub-base with some sort of thermal barrier to prevent the heat from escaping through the ground (secured using a flexible adhesive), followed by the heating mat and finally the laminate flooring goes on top without being fixed down to allow expansion and contraction.

Has anyone got any advise for keeping this job low-cost but ensuring reliable results?

At what point would I put down self-levelling compound to even out the differences between heights in areas which used to be divided by brick walls? The height varies by up to 1/2 inch in places.

Also, can anyone tell me if Mira X Plan Flexible Fibre Reinforced Self Levelling Compound - 20Kg is good stuff?

I have estimated that I need 28 bags.

Price Quantity Tax Subtotal
£10.00 28 £56.00 £280.00

Estimate


    • Subtotal:£280.00
    • Shipping cost:£42.00
    • Taxes:
    • VAT (20%):£64.40
    • Total cost:£386.40
Sounds like a good deal compared to 25Kg Thermoplan Compound £30 a bag, quantity 22 and total £660.00

I've used the Mira X plan SLC. It was alright to use - just took a while to go off..

My experience with X plan was not good. I found it had a terrible flow and didn't mix well. Cheap for a reason imo.

To level out substrate prior to insulation boards a standard levelling compound will be fine, doesn't need to be fibre modified.

Save yourself a load of time, effort, expenditure and frustration and have a split unit air conditioning system installed.

When I looked in to all the heating methods for my conservatory everything seemed too expensive and would'nt give me the control I wanted. The air conditioning heats 18m2 room in no time and it's easy to control the temperature too. An underfloor electric system would probably use 2kw to heat the room whereas my air conditioning system has never used more than 750 watts.

Maybe I should have asked which is the best bang for buck self-levelling compound available and where you get it at that price. So, what would people recommend?

I'm not specifically looking for a flexible fibre reinforced compound given the previosu response.
