Underfloor Running Costs - TilersForums.com

[Chris_32]

20m2 can easily be done on a single circuit pump (if it's in the same room) you probably wouldn't even need a manifold. If you have a drawing of your extension I would be happy to do a pipe layout and a quote for you.

Hi David. I have some drawings of existing heating layout and proposed extension that I can email you over for a quote if thats ok. What is your email address?

Or contact our forum sponsor @Uheat - Jake

That was a bit naughty of David from UFH Store.

Hi Chris, We thought about having electrical underfloor heating mats put in our extension but after we spoke to a consultant it made a lot of sense to use wet underfloor heating. There is a lot more to it than just how many watts the mat draws. You also need to take into consideration insulation and heat loss calculations. IE: The type and number of windows you have in the house the thickness of the walls etc etc... All of this will have a huge impact on your electricity bill.
Also the chances of an electrical heat mat going wrong over a 10 year period is alot greater than a wet underfloor heating system having issues and wet underfloor heating systems tend to be a lot easier to fix. (Not very easy to pull up an electrical mat and change it if it short circuits or malfunctions.)
Most water based underfloor heating systems have a 25 to 50 year guarantee on pipe so definitely something to consider.

Good luck with the project!

And your connection with them is?

Hi Dan,

Sorry I don't know what you mean? We had our underfloor heating installed in 2016. I was just trying to point Chris to someone we found to be very helpful in advising us when we installed our underfloor heating. No one here seems to have mentioned that "heat loss calculations" are the key to calculating and installing an effective underfloor heating system.

Hi Dan,

Sorry I don't know what you mean? We had our underfloor heating installed in 2016 by EcoHeatCool. I was just trying to point Chris to someone we found to be very helpful in advising us when we installed our underfloor heating. No one here seems to have mentioned that "heat loss calculations" are the key to calculating and installing an effective underfloor heating system.

So you arrived on our forum, registered, came straight to this thread, to tell us about heat loss and to link to your supplier?

Fair enough.

No more links though please.

Note that we have a paying sponsor, uHeat, who have been running for a very long time and know their stuff.

Also note that heat loss would be the same whether water or UFH (Insulation type dependent) so your argument to have water over electric because of heat loss in null and void.

Also note that uHeat have a LIFETIME guarantee on electric. Very few have 10 years. And I've never known electric UFH fail ever. It's always the stat or probe or somebody physically damaging the cable.

I'd also give it some time before you say your supplier is brilliant because their system hasn't even done one full four seasons. The floor still has time to fail.

That company seems quite new what actual make did they sell you?

If you don't like links perhaps you should remove the possibility of creating links in the forum?

I spend a lot of time writing forum posts because I think it is fun to help people having built an extension myself. Anyway I'm sorry if I offended you by providing what we found to be a helpful resource, during our self build.

I don't mind genuine people linking. Just not suppliers leaving false positive feedback to link build.

I literally do this all day. Carry on.

They existed for over 30 years as stated on their about us page. We used them for a project when I worked for on the Mary Rose exibition for heating and cooling the environment to ensure the boat didn't decay anymore and remained in a perfect state of restoration.
So I was pretty confident they knew what they were doing, having worked on a heritage site and on a Lottery funded project!
I don't know who told you that about electrical floor mats, but your information isn't correct. I am sure most people would feel happier about having a water based system with a pvc pipe running through a solid concrete floor or similar rather than an electrical device that is more than likely to go wrong. But by all means don't take my word, just google problems after installing underfloor heating electrical mats.
Anyway I just wanted to give Chris some helpful advice. Good luck with your project, which ever solution you choose.

I've been fitting electric ufh mats for over ten years and have never ever heard of one I've fitted failing...wet has there place, so do electric

Google problems with water UFH and you will find some. That's a poor argument.

I can spot a link builder a mile off.

We literally have over 100,000 electricians and plumbers and 10,000 Tilers. The exact three trades to fit and cover up electric and water UFH lol

I've fitted miles of the stuff from about 2001 onwards, not one has failed.

Wow not one person can answer how efficient it is...

Not possible to do due to insufficient data.

Don't mind me while I bump up some older but good threads. If you can contribute to the thread, go ahead. But if it's nothing for you then don't reply and it'll soon drop off the What's New page etc.
