Has anyone on here ever used the JK Underfloor system or got experience of it please? Got a few questions I wanted to ask.

If you mean the wet floor system which I prefer anyway over electric then it is better.

water is a bit simplier to a degree as its cut and slot your pipe in and test for water seal per run setup

electric is a bit harder to a degree yet simple as its best to test at every stage of the lay.

however it has its problems when doing long runs

both can be wired or plumbed into zones

unlike a wet system if the wire fails not long after then your stuck with a non working system

Yes that’s the system. The cutting into the floor assumes that there is no insulation in the floor so wondered what people’s experience was in that situation. Especially those that have fitted engineered wood over it.

Yes my whole house is underfloor heated (we system) from soleheat.

Hands down the best thing ive done in the house, takes a while to set up and balance but the room heat is atmospheric rather than hot spotted to a radiator.

Cost wise its no difference to rads.

Avoid electric it costs the earth to run and doesnt last.

Electric doesn't cost the earth to run, so long as the insulation is sufficient. I have been selling it for 20 years and have it in 3 rooms, all using as a primary heat source. In accelerated tests the system burnt out at 72 years, so we'll over the lifetime of the floor covering.

The only thing I'd say is check the manufacturers guide lines around running temperatures. When it comes to wood even engineered this is usually quite low due to stability issues.

I've seen lots of issues with wooden floors over the years all bar one which turned out to be a water leak, were installation problems.

Not sure how they ran the tests, and worked it out. Guess they ran it at a higher amplitude 24/7 until it burnt out.

As the lifetime of the average floor is only around 10-15 years it will outlast it. These systems are only low wattage 150-175 on average.

Are you sure it doesn't?

Are you sure that the led bulb you bought will last the 10 years they state, or that your Toyota transporter will run for over 1 million miles?

Only thing guaranteed in life is taxes and death.

your simply quoting what a company issues out to there customers

therefore what you quote is actually untrue.

Really the company hopes you change it in 5-10 years

you also cant quote it the same as 2.5mm wire either even though that lasts a whole lot longer

pex pipe even I cant say how long that will last, but copper pipe I can do as that has lasted well past the test of time.

Nail on the head, the wire is 2.5mm. I never said it was anything else.

Not even really sure how we got here.

I was offering advice on running temperatures and the costs from my own personal experience.

Quoting some manufacturer information I get shot down, but hey ho.

I don't have a liking for either system to be fair. Pipe has its place as does electric.

With a concrete floor electric is the simpler method. Insulation board down, then the heating, and then the covering.

Wet system. Dig up the floor, usually insulate by a suitable means. Pipes in, concrete back over and a possible new dpm. Or make a floating floor surface. Then the floor covering.

Obviously there are sometimes exceptions to this depending on the age of the property. I'd always advise a proper survey if folk are unsure.

Wooden floors not so much trouble, even easier on new builds.

I don't have an issue with either system and can source a wet system if preferred.

It's hard to convince some who are so bought in to the wet systems that electric isn't that expensive.

The horror stories you tend to hear don't insulate well and you need this with both methods for it to run most efficiently.

Good luck op with your choice, and hope you find the advice you need.

wrong the heated wire only measures 2.5mm as is low voltage

2.5mm twin and earth is different as that is your plug wire that takes alot more stick.

makes no difference if its electric or wet as you quote insulate floor same can be said for a wet system

25mm insulation then pipe in with insulation pipeflow as pex fits inbetween it

which gives 50mm lift to your floor

if fitted to the concrete not only the tiles become a thermal store so does the concrete below taking a slight bit longer to heat up but lasts way longer over just a tile heat store.

you will find that referance under

Thermal storage walls

As you fit it so do I, I also rip it out as well when its failed over a certain time of years.

exact opposite when its a wet system users have a choice and there is a cost within either system the electric side been the cheaper alternative.
