Oil fed boilers - advice sought
While we're on the subject of boilers at the moment on this forum - any advice for an oil boiler?
I've currently got a vintage Unidare Jetmatic (50-70KBtU), retrofitted at some more recent stage with a Sterling 40 burner. It works, i.e
produces heat. However, its noisy, exhaust gases leak from the boiler and are drawn back in to the house from where it vents (I guess building regs.
are good things). It lives in the garage, with all the pipework carrying water and oil buried in concrete.... weeping a tad. The garage floor needs
re-laying (yes it's that bad), so there you go, ideal time this spring to think about a fresher boiler (outside?). Currently its a
'conventional' system, (fresh looking) hot water tank in roofspace.
My hot water requirements are not vast.... what's the best way forward, a combination boiler? or stick with the current tank system. Ideally,
I'd like the thing outside, but that's mainly to clear the garage foor but also because the current system wants to kill me.
Any recommendations?

have heard good things about the worcester combi oil boilers. Grand parents had one and it lasted 20+ years and was super efficient.

Personally I would go for a Biomass boiler, take part in the renewable heat initiative and recieve 7.9 pence for every kilowatt of heat I create and
have free heating for the next 25 years.
Wood pellets work out at around 4.5 pence per kilowatt.

I looked into this last year and will be going for a Mistral boiler this spring. On an independent installers advice I will be going for a
conventional boiler, not a condensing type. Oil fired boilers are not covered by the latest regs for gas boilers.
He tells me that the efficiency of the Mistral conventional boilers is within 2% of a condensing boiler, a lot less hassle to run and several hundred
pounds cheaper to buy. A mate has a Mistral boiler and is very satisfied with it, and they are made locally too.(Telford)

How do you get the subsidy? This would be an ideal system for me I have the land to collide trees buy can't work out how to get the subsidy.
Any pointers much appreciated

Having recently had a combi boiler fitted, I have come to the conclusion that they are crap! They are more efficient in gas use/recovering exhaust
heat but what you save in gas you lose in the amount of water you waste waiting for it to get hot. It's crap for a shower as it doesn't
maintain the temperature like a tank fed one. oh how I wish I had the old one back with the hot water tank. If you wqnt to wash your hands hen the
heating circuit is fired up, you scald your hands.
So my next step is to fit a small hand wash unit in the kitchen and an electric shower.
My gas use is the same as it was before in spite of more insulation in the loft and having had the walls done.
Conclusion; combi boilers are green in the way that electric cars are. NOT

I would have thought it might be easier to get a Unvented hot water cylinder fitted (can be placed anywhere and fed directly off the cold water main)
and only use the 'heating' side of the combi then when the combi needs replacing you can replace it with a simple system boiler.
If they have the space and don't mind it costing initially that's what I'd advise most people to have, there also the backup option
of immersion heaters in the cylinder aswell then.

The boiler you fit has to be MCS approved and so does the installer, the installer will sort out the certificates of registration then you recieve the
tariff paid for by the government for 25 years look up the renewable heat initiative on google

It's a no-brainer! Pity the introduction is delayed until October but I suppose it gives loads of time to sort out paperwork
Cheers!

I had an immersion tank as backup, but on the start of day two of the installation I was rushed into hospital with a suspected heart attack and the
now unsupervised muppets removed this and all the piping, including the new feed piping that I had just put in for an electric shower.
