Underfloor Heating in a garage ? Anyone done it ?
Discussion
Doing large rebuild including garage. Old garage was cavity walls and double glazed, so reasonably warm. Building new one with thermal blocks, cavity insulation and warm roof. Also putting insulation on the floor.... so why not UFH too ?
Anyone else done this, or can suggest if a it's a good idea or bad ?
Engineer has said they work on same floor loadings for house and garage. Flow screed man is suggesting 75mm screed in garage of a different material than the 60mm screed that is going in the house.

I have a large garage build in the pipe line (20m x 8m) and i will have wet underfloor heating, think the spec was hardcore, 150mm of concrete then 100mm insulation pipes clipped to that and then 75-80mm of screed.
I will have a mix of car traffic and heavy machinery.
If you do a search on here there are 2 threads from people who have done it.
The cost is not that much in the grand scheme of things

Done plenty of garages with underfloor in the last few years.
Pipe spacing can be generous (unless you want to get it to 25), ie 300 spacing rather than 150.
We usually do a double garage with 100 metres of pipe.
Note if you are using a boiler for the heat source the temperature of the water going into concrete shouldn't be more than 45, so you'll need some sort of tempering valve.

Bit of food for thought from Canada , when temps are below freezing and you bring a car into a heated garage the condensation is dreadful , fuel tanks / pumps for a start . Admittedly our winters are a tad more harsh and longer but give it some thought ,know you guys have a liking for winter tires nowadays LOL .

Only real question is whether it's worth the cost of installation and running for a building that you may not spend that much time in.
Is that you sweetheart posting in secret ? As I've told you, it's the most important room in the house.chippy348ts said:

Magic. That's confirmed the spec. The re-inforced slab is down. 100mm Recticel on it's way. Flow screed fella is doing some 75mm fibre re-enforced screed.I will have a mix of car traffic and heavy machinery.

isn't the warm up time going to be a bit annoying? How long are you in there for
I kept the heaters on in the old garage. Italian V12 and an old Ford to keep comfy. It will stay warm. Just cost less to do so now.f

Super. Thanks for the useful info. I've just ordered another Henco manifold and mixer/pump assembly. Will put this in same as the rest of the house, but wider pipe spacing.Pipe spacing can be generous (unless you want to get it to 25), ie 300 spacing rather than 150.

Ha ! I used to work in Chelmsford. MA, not Essex. I know about the cold winters. I'm in the south of the UK, so worse case if I take them out in winter, it's leave the windows open for a day or so.I am just preparing to start work on a new build detached garage/workshop at the bottom of my garden. I like the thought of underfloor heating as I spend a lot of time laying on the floor under my classic campervan year round. I have been wondering if underfloor heating would withstand the weight of cars on it. Also considering solar panels on the roof for electricity. Located in the South of England.
Underfloor pipes, definitely.
The lowest capital cost for heating would be straight electric - the lowest running cost with reasonable capital cost would be a small hot water heat pump.
A 3.5 kW unit runs at around 800 watts.
The problem in the UK would be finding such a unit at a decent price.
Hi, wondering how you guys got on with wet UFH in garage? Would appreciate feedback as we are about to build garage and seriously considering this for number of reasons. Spend at least 3-6 hours in current ( freezing workshop/ have an old Triumph/ daughter is athlete and trains in outside gym 6 hours a week…which is an old polytunnel….its baltic and not great in winter.
We are definitely using wet UFH, as upstairs of garage will be an office/ hobby room….using ASHP from nearby house build. Thinking of insulating floor and walls to “accommodation standard”.
What not sure of is how thick floor above ufh has to be to enable car use.
Welcome advice and experiences.
