new oil boiler and storage tank

[kansaskid]

I have moved into a new house where the existing mistral boiler has had its day(30 odd years old).i have planning permission for an extension and when the house is done it will have5 bedrooms 1family bathroom and 2ensuites plus kitchen utility and cloakroom. I have a cylinder in the bathroom at the minute I would like to do away with to make bathroom bigger.Have a small boilerhouse 3ft x5ft where boiler is housed.What sort of system-boiler etc would anyone recommend! Any idea of costs? Thanks

If it has to be oil, then the Grant Vortex condensing oil boilers get a good name.
Don't however get a combi oil boiler as they are complex, expensive & unreliable.
An unvented stainless steel hot cylinder would be best, if you have the space & providing you have good pressure & flow from your mains water. Can you not have a large boiler room built for to house both the boiler & an unvented cylinder?

if works being done anyway, as above plan for a twin coil solar cyl to benefit from all that sunshine, and keep boiler and cyl in one place.

As above but PLEASE put a plug socket in the boiler room (for the service engineers vaccuum cleaner )

Warmflow boilerhouse model, complete with a correctly sized expansion vessel, unvented cylinder (dependant upon water pressure and flow rate) and don't forget the frost stat.

Don't go for warmflow bit tat imho
Grant vortex is the best

At least in the boilerhouse the grant vortex won't cause a lot of damage when it's leaking all over.

Personally I work on oil boilers all day long, avoid a combi at all costs. Worcester bosch oil boilers tend to be awkward and pigs to work on. In my view grant or warmflow. I personally have a warmflow external kabin pak which works a treat. From a servicing point of view grant + warmflow are practicly the same. Just the warmflowhas a slightly higher burner making it easier to service.

I have fitted and seen hundreds of oil boilers and yes any boiler can leak but I have only seen a few grants do this but a hell of a lot of other makes and especially warmflow
