Central Heating - quote
Discussion
Just got the report through last night, he wasn't that advanced!
RHI is less than I hoped for @ £2493 PA so a projected return of £15600 ish over 7 yrs.
The quote for the system is 23k, but includes about 1.5k for weather controls. Not convinced we need them TBH.
So if we assume £21.5 including VAT then its costing me £6k all in over the period of 7 yrs. That's a still a saving over the oil system, but I don't know enough about fuel consumption of pellet vs oil vs electric to know how much the savings will be in terms of energy bills yet.
If I add cavity wall costs on top of that and interest payments on top of the 10k interest free, it may become marginal.
Plumber however said he would tweak his boiler sizing and quote according to what came through, so it may come down a bit yet.

You should be looking to pay about £13-15k for the boiler install with controls, your house plumbing/radiators on top?RHI is less than I hoped for @ £2493 PA so a projected return of £15600 ish over 7 yrs.

That's about right from the breakdown they gave me - a fair chunk of the £21.5 includes installation of radiators and pipework etc.Also includes a new water tank etc

Windhager Biowin Exklusiv 26kw manual feed (200kg)is whats listed, but they may change that according to the report (new quote due shortly).
That's about 8.5k including VAT.
Wolseley indirect cylinder unvented is about 1k.
That seems sensible. I've got a brand new(still boxed) OSO unvented cylinder here if you want to save a few quid That's about 8.5k including VAT.
Wolseley indirect cylinder unvented is about 1k.

Do you need a 26kW. Ours is 21kW and our heat load is 47,000 and the boiler works fine. I wanted a 26kW but was told over sizing is as bad as under sizing as it will be on then off for long periods. The most efficient operation is when it modulates in and out without losing too much heat. Might be worth a quick call independently to Windhager technical people and tell them your situation re heat load, size of property, usage, how well insulated etc. From memory the difference in cost between 21kW and 26kW was about £200 so negligible.That's about 8.5k including VAT.
Wolseley indirect cylinder unvented is about 1k.

Well what a faff.....
Assesment says cavity walls - local people come round and say nope not a chance. Timber framed gable and you cant cavity insulate a mixed construction due to the risks. They also do green deal assesments and the position of the house and construction meant it should never have been on the report.
Fine - get letter from them confirming, call plumber who says great but just check with OFGEM on the RHI.
Phone OFGEM and they say not a chance - you have to get a building surveyor out with a signed form..."sigh"...
Phone surveyor, he says assessor was wrong try him first, assessor says wont change report - and now not responding to me.
Surveyor out this morning and within 2 minutes said timber frame and happy to sign forms (£60 later).
So maybe I can actually get on with this now!!
Sell the house at this rate...

We've just had ours up and running in the past 24hours. Once done I'll thread it all. This is the first time the house and had central heating.... Its amazing Still not found a car either
Be interested to see how you get on with the larger boiler. What was the heat load? Still not found a car either We kept ours fairly low for a while not to dry the house out too quickly, and have turned it up gradually but still only at 18 degrees which seems warm enough. When its really cold we fire up the wood burner to increase the heat in the room we mainly sit in, but can now leave the doors open to circulate the heat.

The boiler is doing its job regarding heat. We've a roomstat upstairs and downstairs, along with an external weather sensor, currently running it on a setting that takes a reading from both. Sensors in the hallway set to 16deg, seem to give 18deg in the rooms....
The one thing I am struggling with is hot water out of it. Its got an integral 15m coil which heats up water as it passes though, my mains cold flows at about 58lpm currently so i'm asking too much of it, so i'm going to fit some flow limiters to the shower, of 12-18lpm each to see how it gets on then. The boiler is designed to give 'nearly unlimited' hot water at 12lpm flow though the coil, so bringing it down should help.
I'm currently leaving all doors open in the house, to give some air movement and it seems to be working. The whole house is now 'warmer' even when the heating is off.
For the heat load, I think its been measured at about 31kw for heat, plus water. Various ways of measuring really give us a need of 26-36kw for heat, the building type means we 'loose' heat, however I think its bo&&ocks. Once the mass of the house is warm it stays warm.
How are you getting on with yours? what are you controlling it with?

Great. Over 12 months now and used 7 tonnes so £1,700 for heat and water but saving £600 on electric and now have heating which we didn't have previously. The RHI more than covers the boiler purchase and install plus costo The boiler is doing its job regarding heat.

Heat load was just over 41k and water 6k. Same building type as you I think - 350 years old (ish), single glazed, solid walls, 2 open fires (with balloons in at the minute) and 1 woodburner, soon to be 2. Conservatory attached to the kitchen is the biggest heat loss as its all glass with polycarb panels on the roof - would like to get it down and put a solid roof on but would have to do it in hardwood and it would cost a fortune. Did feel a draught moving through last night but not sure where from. 2 x wireless Honeywell 7 day controllers (CM7xx) which are really easy to use and has a holiday mode. Water is fine - we have a Range something or other but the water pressure is excellent (hot and cold).

FFG, is yours running a thermal store? Its a strange experience seeing the pellets go and and knowing thats actual cash! I think we're going to budget for 7 tonnes a year. So about the same. Our houses seem very similar in construction, we do have DG but its really old stuff, to counter that we also have 2 large single glazed windows. What are the balloons you've got fitted? I've another inglenook to fully open up so could do with a way of sealing it slightly till we know what we're doing. Heat load was just over 41k and water 6k.

Heat store/thermal mass is a Range Tribute HE 180ltr, with 2 small expansion tanks on the wall - one white and one looks like a bell end. Mains pressure was good before it was fitted. The balloons are chimney balloons:

Stop all the heat going up the chimney whilst you're sorting out the work. We have 1 we don't use at all yet and the other occasionally so you need to take it out before use, but its not difficult.

They're great! Makes sense, I'm going to have a measure and see what size I need. I've just ordered two flow limiters with 12lpm and 15lpm inserts to see how i get on with the water. I think I'll have to plumb in the water cylinder though to take full advantage of my high flow rates.The balloons are chimney balloons:

I loaded the hopper with 420kg of pellets a week ago, its got about 20% left, the heat has been on more than usual as I've sorted out leaks, drained down etc, so 'harsh' winter usage really, hoping it lasts anther 3 days which would put it bang on expected use. Our problem is that as we've installed in winter, it seems expensive to run but its not had any averaging for the 6/7 months the heatings not on.

We only used a bag a week during the summer to heat the water, so about £2.50 per week. It'll use more until its dried out and you've got a good base heat. We set ours to 15 degrees minimum so its always reasonably warm and it ticks over nicely with a boost on the morning and early evening.I loaded the hopper with 420kg of pellets a week ago, its got about 20% left, the heat has been on more than usual as I've sorted out leaks, drained down etc, so 'harsh' winter usage really, hoping it lasts anther 3 days which would put it bang on expected use.
