100KW gas boiler for domestic install!

[infromthecold]

Right I have been to house and measured the rads. All are Quinn double convector details listed below. Need 34KW to drive the rads so not 100KW. Can anyone recommend a boiler with correct capacity?

Cheers

Get your new installer to do that. Bin the current guy.

I spoke to engineer today to say about 34kw load so why such a large boiler and he said he had a TSM from Worcester attending site tomorrow. I didn't know they had such a service so I called Worcester and they do indeed have such a service. I spoke to technical pre-sales asking for an opinion or insight and they said they couldn't give definite answers without seeing everything.

One thing they did mention is heat loss in the pipe work if the lengths are long.

Can this be so bad that it needs a lot of extra power in the boiler to compensate?

Do all the rads go on one loop?

Any insight or suggestions gratefully appreciated.

Cheers

Just forget this guy ever mentioned 100kw. It's now irrelevant. I think I'd be looking for a new installer tbh.

 

[kirkgas]

You will only need a 100kw boiler if you intend to turn the house into a marajuana factory to supply your whole town
Get someone else in to suss it out, very rule of thumb is 2.5-3.5 kw per room ( this allows for variables of room size) as a quick calculation, so a 100kw will do about 30 rooms haha
As suggested go with a system boiler and unvented cylinder you won't regret it

 

[dancinplumba]

100kw of lights will do a lot of plants and the heat off them will mean you wont need a boiler 🙂

How come you two seem to be experts in growing weed?

No wonder you're both such chilled characters. Roll us a duuuuuby!! LOL.

I knew kirk didn't buy that Lamborghini from working in the training centre!

I've never tried it, but I've been in 100's of houses where they were smoking it, and one many years ago in a multi storey flat in Glasgow which we got called out to in the middle of the night flooding flats below, police got called to attend for forced entry and the whole flat was full of ants, with a 10" gap path to walk round the whole place, the heat lamps were rigged of the power for the lift and the temp was sky high, as soon as the joiner opened the door the smell hit us and the cop radio 'd in for the drug squad, brilliant engineering and workmanship to set it up haha
Don't mention the Lambo it's away back and now I'm bored and invisible I'm my XF Jaguar haha

That was Tamz. He's a coke lord, not a weed grower. Get your facts straight!! LOL

 

[Dannypipe]

Well I'm not getting into the thorny subjects of drugs, and what we've tried or haven't.

Suffice to say that a nice cold beer is the only inebriation I like. Or scotch, or brandy, or wine, turps.....the list goes on!!

nah, he's just my number 2 😉

Right I have been to house and measured the rads. All are Quinn double convector details listed below. Need 34KW to drive the rads so not 100KW. Can anyone recommend a boiler with correct capacity?

But you don't know if the radiators are correctly sized?

Use the Whole House Boiler Size Calculator to find out what size boiler is required.

It does not matter if the radiators add up to more; it just means they can run at a lower temperature.

Worked out what house requires previously and size, volume and construction need 32kw. Rads output 34kw.

Worcester TSM has been to house today to talk to engineer and he has said it needs a 65KW boiler and a U16. I am trying to get the contact details for the worcester TSM so he can explain his thinking.

 

[Roger Welton]

Worcester rep not made his quota of GB162 this month?

 

[kirkgas]

If the rads req 34kw why does it need a 65kw boiler????

What the hell?

I implore you, please get another heating engineer round. This stinks. Even if you do it on a Saturday and just pay him to specify the system for you.

the 42 cdi is sufficient and a extra expansion vessel.
