Gas central heating

~Divine~Wind~, amazing price for all that AND it's a Worcester. Obviously very cheap getting things done up north. :eek:
 
I had a quote for my top floor Maisonette to install Gas CH and the company quoted 4.5k for 5 rads with TRV'S new boiler and install pipework and commission.

In the the end my Dad and I installed it all bar the boiler which my neighbour installed and commissioned, runs his own business.
 
Yeah I thought it was a fantastic price, they only took 2 days too.
Me and the missus' dad were here to rip up floorboards and to do the dog work where needed to save them a bit time.

Really happy with the work theyve done, didnt realise til it was all in and running how much it actually needed done :p
 
I would say go for Worcester or Vaillant, minimum 28kw. Worcesters have a 7yr warranty, Vaillants 5yrs.

RE: Pipe sizing.... The gas will get sized accordingly to fall in line with gas regs, its not just a case of picking a size! Depends on how far, and the gas rate required by each appliance connected..
Heating pipework will generally start in 22mm and run in that for several metres tee'ing off into 15mm for the rads...If you have a large property these sizes will be bigger...But if that was the case you wouldnt be having a combi!!

DHW pipework should be in 15mm (again unless you have a large property) Mains water usually comes into a standard property with 15mm at the stop tap, so increasing that size to 22mm at the boiler has no benefit, and actually has a negative effect on the DHW performance! A larger pipe takes longer to empty, so you wait for longer when drawing hot water...Not great if your on a water meter.

I can only go with what I have in my house. My Vaillant boiler is now 16 years old (fitted in Aug 1996) and it hasn't missed a beat yet (touch wood). It gets an annual service from British Gas and passes with flying colours.

WB only have the 7 year warranty if installed by an approved installer tho no?

AFAIK it was 22mm used for the main "arteries" in the Loops then Tee'd off to 15mm for the Rads. One of the guys that did me a quote wanted to do the 22>15>10 tot he rads, tbh I felt as if this was a bit of an excess expense that wasn't needed. Also if larger sections were 10mm then AFAIK you can T off from 10m pipe. Not really sure how it affects pressure wether it be positive or negative or nowt at all.
 
10mm is acceptable for small radiators on a small system. Otherwise steer clear!
You can generally use 10mm for the upstairs, but stick to 15mm for downstairs, where the rads are usually larger, and have the furthest pipe runs from the boiler.
Usually 10mm systems are installed in modern properties (new builds) and work from a manifold, in house that is much more energy efficient than older properties.

And yes you have to be an approved WB installer to get the 7yr warranty, but you should be able to find a local installer, it wasn't anything out of the ordinary for us to become approved fitters!

My personal choice would be a Vaillant, but they are not the cheapest, but a boiler is an investment for 10yrs + So don't scrimp on it, cos you've gotta live with it! :-)

Finally found a decent place to do my heating. Should be about £2500 for a combi boiler, 4 radiators, a towel heater and fitting. Flush and warranties included too. Seems like a good price considering i am in the south. Going to get more details over the next few days. Should hopefully have proper heating soon :)
 
Had a Main one fitted by a gas safety mate last year. All good, he recommended Main as it's all the same parts as Baxi and Potterton. He did though recommend getting one larger than it suggests you need, so that you don't have to fight over the hot water :)
