Got a quote for a new oil boiler. Does it seem reasonable?

Description of works: Worcester External Heatslave II 25/32

1. Lay dust sheets to all working areas. Discuss programme and protect areas to clients’ request.
2. Take out the existing external regular boiler and clear away.
3. Carefully take out the existing hot water tank, cold water tank and all associated redundant pipework and clear away (asbestos roof tanks will not be removed, they will be double wrapped in polythene and lift in the loft).
4. Supply and install a Worcester Bosch External Heatslave II 25/32 Oil Combination boiler, located in the existing position with a standard flue system.
5. Supply and install new pipework from airing cupboard to be installed and lagged externally and connected to new boiler (please note these will require additional ‘boxing in’ and protection from external elements to prevent from freezing).
6. Supply and install a condense discharge pipe to connect to the nearest waste pipe, drain or soak away.
7. Supply and install a ‘lime fighter’ in line scale reducer.
8. Supply and install an auto bypass valve.
9. Supply and install a Google Nest heating control.
10. Take out any redundant pipework and supply and install all necessary pipework. Insulate pipework in unheated spaces.
11. Carry out a full ‘powerflush’ of your system. This involves carrying out a thorough clean of your system with a powerflush machine. Each radiator will be cleaned individually, in situ, with the water circulated in both directions. The entire system is flushed and drained and refilled with clean water and a system corrosion inhibitor.
12. Carry out all necessary electrical work and issue a minor works certificate. Register any qualifying works with NICEIC, a ‘Part P’ certificate will be sent, if necessary, to you directly from your local building control office (required if you sell your home).
13. Supply and install a fire valve to the new boiler.
14. Carry out a commission of the oil boiler, issue an OFTEC commission certificate, register the installation so that you receive the ‘letter of compliance’ from your local building control office (this is required if you sell the property). Register all manufacturers guarantees and installation manuals.

Doesn't seem too bad. Personally I'd fit a Navien, which is a better boiler and about £900 cheaper.

Maybe, but was it your idea to go for a combi, or did the installer try to push you down that route? Might not be your best option.

 

[Cha0s]

He did suggest it.
We want to free up the space taken up by the water cylinder (in the bathroom) so a combi seemed like a good idea.

I've also been thinking about getting quotes for biomass boilers. Possibility of a govt 5k grant.

 

[muggles]

I've never seen a biomass combi boiler, and you need much more fuel storage space for biomass than you do for oil.

 

[Cha0s]

We have the space for pellets. Just wondering if a 5k grant will help. Or if a biomass boiler will be more expensive

 

[Cha0s]

But with biomass we would need to keep the hot water cylinder. So that's a negative

 

[muggles]

Biomass boilers are more expensive, and you need a lot of kit to go with them. You would very very quickly get fed up with a manual feed one (been there and done that with a customer) so you need a hopper and auger setup, and of course a building to put it all in. You need to store about 3-4 tonnes minimum. That £5k grant gets swallowed up fast. It's not a cheap fuel, either.

 

[Cha0s]

Okay. Thanks for the advice. I'll stick with oil.
Any opinions on the oil combi idea.
As I mentioned. Removing the cylinder would be ideal to free up the space in the bathroom.
Do you think talking to the place that quoted and asking what can be done to get the price down is a good idea.
E.g. I could remove the old tank and associated pipework myself. Leaving them a blank canvas to put everything in.

 

[Koolpc]

Get a few quotes.

 

[lostinthelight]

How far is the boiler from your outlets compared to where the cylinder is, retaining the cylinder also gives a good reserve supply of hot water in the event of a power cut

 

[Jackrae]

Would have thought that line 11 should be done before line 4

 

[fixitflav]

retaining the cylinder also gives a good reserve supply of hot water in the event of a power cut

And a supply of hot water using the immersion if and when the boiler has a fault.

 

[Cha0s]

@lostinthelight Boiler and cylinder are about the same distance from hot taps etc. The boiler is outside on the ground floor. The cylinder is 1st floor basically above the boiler

 

[Cha0s]

Would have thought that line 11 should be done before line 4

Probably. I assumed they'd clean out the gunk before installing a new boiler
