10.4 kw still the max output? No power shower but does the job?
Exactly , but I'm relatively clean . it's mira sport airboost , ideally needs a pre warm system in the winter as it's straight off the mains supply.

Ah, not much has changed! Them in wales, pressure seems to be entirely dependant on water temp coming in. Pre heaters sound good but lots of faff!

As cheap if not equally cheapest to run.
Systems have spf or COP of 3. this means for each kW of heat is a third of a unit of electricity. You pay 15p it'll cost 5p. Oil, 3/4p, LPG 9p, gas, 4/5p per kW of heat. Log burners, even if they are free it's time, cost of logs if bought and cleaning grates.
If you are lucky enough to have a converted barn/stables as well as farm house then you can qualify for district heating and non domestic RHI. 20 year payment. This then means a free system, rhi support to buy another, and tier 2 payment which means you only pay 2.3p per kW of heat in the depths of winter.
Possibly the best bang for buck heating system on the market

Any recommendations for Ground source heating companies or the where to buy the kit. Would want to do the digging work etc... myself
No,expensive rubbish that in a very cold winter don't work

Rubbish, if that's your experience you've had a poor system installed.
I'd happily recommend Ochsner heat pumps; our system is very good and we're pleased with the performance of it. It's providing heating and hot water to 4 properties and has been installed for 2 years now. Ochsner also oversee the design of the system before the installer orders the pumps so there is some reassurance that the outputs required will be met. Happy to discuss our experiences via PM if you're looking for more information.
where do gsh get their heat from ? thats right the ground ,what heats the ground ,

In our case? Not the sun directly if that's what you're inferring as we're pulling heat from 125m below ground. We only need 9C incoming in order to generate 55C at any hot tap on the farm, any well designed system is capable of that no matter whether it's a borehole, ground loop or lake collector. There are entire office complexes heated in Austria in the same way, even in winter
.Oh and we've got an air source heat pump that keeps our log cabin warm even when it's -12C outside too
It's either witchcraft or physics, one or the other!

You're out of our catchment area, but I'd be willing to vet and analyse systems you get offered?
We only cover Northwest.

Sorry but the RHI for 2 units i.e. Sub <200kw is pretty much dead. Those early in did ok - think I getvabout 9.2p/kWh but now it's so low I'd look at heat pumps, pv and fossil fuel top/back up.

No for the construction but I could provide responsibility for system sizing, this would of course come with consultancy fees if I am to become libel in any way.

You are wrong. RHI will pay for the system twice, tier 2 provides kWth at 2.3p. If you are lucky enough to have solar then further running costs are efficient.

I think we will have to agree to disagree here. £ for £ I would have said investing in a biomass boiler in the sub 200kw unit will give a worse return than others such as heat pumps.
He will have to get other buildings involved to make biomass viable, the secondary side could cost quite a bit of his house is some distance away. A good example of the grant tail wagging the dog.
Tell me, what's the current cost in pence / kWh in chip and pellet?

Sheesh, got out of biomass 2 years ago only pellet.
So tonage started at £220, went to £240 after 6 months but manage a haggle on £225 thereafter. That was 12 months ago.
What's the cost now?

How can you say biomass is the way forward if you have no idea what current fuel costs are!?
Chip was about 3.5 p / kWh - not sure now but doubt it leaves much profit for a small system before electric / maintance etc.
Straw costs me about 0.5 pence but that's different to a chip system.
As I said before, £ for £ biomass won't be as good as others now, unlike in the hay days of 2012

Never have championed biomass. Heat pumps are the units to have.
£for£ heat pumps are now

Your figures are a figment of an illusion with straw. Tell me, how many hours/days are wasted annually maintaining your boiler?
