Sanity check for new central heating system quote

[Stalemate]

I bought a house last year which had very inefficient electric heaters and no gas connection. The house price worked out cheaper even if I do all the works so I went ahead with it.

I now have a gas connection installed and am in the process of getting a full central heating system. The house has two-floors and contains three double bedrooms, kitchen, toilet, living room, hallway and landing.

I have received 04 quotes and am planning to go ahead with one of them based on the company's experience and cost. Posting the quote here for a sanity check to ensure everything is suitable for the size of my house and nothing is missing.

Total quote is for £4400.

Also, what documentation should I expect at the end of this install? I have read about the gas safe certificate only.

Thanks.

Are they installing new pipework for radiators? If so, you might want to clarify whether it will be copper, which is what I'd want, and where it will run (hidden underfloors, surface mounted, boxed, etc.). There's a significant difference in price between visible plastic vs copper nicely hidden beneath floorboards and you need to be clear which you are getting.

24kw combi 28-30 kw I would recommend for a standard house

Seems a bit cheap

boiler and bits around 1.5k -2k

Rads and pipework around 1k - 1.5k

So I’m 70% sure it will be done in plastic and 10mm drops

TBH I would recommend 15mm drop to all the rads and in copper better flow rate less chance of it blocking like most 10mm plastic do

As for certs / forms

You should get all the manufacturers warranty
Building regs form might take a week to come but chase this up if you don’t receive it

Overall price appears very reasonable. However, unless you have just posted a few key points.
This quote/estimate is also very vague.
I agree with Shaun, specify Copper and confirm on pipe runs and routes.

All above, no harm in getting detail correct, has chosen contractor supplied his gsr credentials, and will it be the person you have met not someone else, sub contractors can be a nightmare Rob Foster aka centralheatking and always copper upstands to radiator valves
plastic looks crap and goes yellow

Personally I would advise a higher output boiler to give you a better hot water delivery , a copper install would be better but I have no problem with a hep2o hidden with copper drops as long as it installed correctly , ensure you have a 28mm copper gas supply installed from the meter to the boiler, the quote you have received is very very reasonable but as others have said its a bit on the low side as there is probably 3k + of materials ask your installer for a breakdown of the materials he's using and a detailed description of how it will be installed better to proceed with caution and know exactly what your getting for your money. Ensure the System is cleaned on completion and inhibitor is added, the Boiler benchmark is completed and warranty is registered with the manufacturer and Gas safe. Cheers kop

I'm with the majority in saying I would install a bigger output boiler purely for better hot water flowrstef.

 

[townfanjon]

At that price its sounds like plastic , pay a bit more and go copper . Yes agree with all above 24kw would be a mistake , you need 30 kw , and it wont be that much more expensive.

At the risk of being the victim of a frenzied mob by my esteemed colleagues, I'm going to lob in an alternative based on a recent conversation with the tech director at Viessman... Sorry.

First. Get a proper heat calc done on your property. Understand what its maximum heating requirements are. What that does is ensure you are buying the smallest boiler you need which means its most effective and, oddly, lasts longest. Based on what I know, you'll need more like 15kw.
Second, do not, yes do not, buy a combi boiler for reasons already alluded to here. To do an appropriate water flow for a three bed house you need to severely oversize the boiler.
The best option to align with my first point is an unvented cylinder (UVC) with good quality pressure and qty of stored hot water. With standing losses so low on UVCs these days and recovery times so fast, all you do is set heating of your water to be outside the times of central heating use.
Lastly, invest, yes invest, in top notch controls so that your ongoing running costs are minimised.

Currently, IMHO, you are spending far too little on a system. Spending more will pay you back big style over time. So, if you are staying in this house, invest in your own future.

Let the tirade commence

If the installer needs to add a fused spur for the boiler, then the electrics will require certification too ......... which may mean extra costs upgrading and / or adding the necessary equipotential bonding cables too

 

[Bogart]

Removal and disposal of old boiler? Is there one ? You only mention electric heaters and no gas supply. Oil maybe?

 

[quality]

If its a new install from scratch I would recommend a heat pump

 

[Scott_D]

A bit cheap as the rest have said
Pro 28 is about £100 more

 

[Riley]

Cheap I’d ask for more detail

And as the OP hasn't suggested where in the UK they are , we are simply speculating. Location matters A LOT

 

[Gasmk1]

plus 1 for the larger output and most combis can be adapted for system size so it wont be putting 28/30 kwatt into heating just the hot water

Yorkshire Dave is quite correct especially in principle. . Rob Foster

The op scheme is penny pinching and doomed to be inadquate ,

Shakes his head , again , how the fec can you call the op a penny pincher, a one bathroom house is absolutely spot on to install a combi how can you call it inadequate? , how do you know he has room for a cylinder and boiler ?

Stop shaking your head I was wrong, there is another one concerning a Georgian building
which is penny pinching

Agree we don't know. We wait with bated breath...

 

[king of pipes]

We won't shoot you down in flames Davy boi your recommendation would work , but in reality the op has made his mind up to go the combi route bud, I totally agree with the kw needed for the radiators I see it all the time when gas rating a boiler on a install or service , but as we all know to get 10 litres plus a minute hot water you need 30kw or more .
