Real world heating cost

"As with all these building energy issues, the Navitron & the Green building forums are a useful source of info."

 

Amen to that

I would be looking at a 4-6 cyl diesel 3PH generating set.

BUT, harvesting the otherwise wasted heat.

Not a poxy wee off-the-shelf mains gas fuelled pipsqueak/lifestyle CHP set.

The bonus for me would be the 3ph electric.

My 3Ph electric usuage would be so intermittent/some days only /some daylight hours only, that if needs be I could either use the 3 PH to drive the GSHP or satisfy my demands with the GSHP switched off.

ah, with you now

Sounds like the CHP situation is still unchanged then - utter shite

you can get off the shelf units like this, a mate is looking at one for his new farm, 50% cheaper than putting mains in

I,m hoping to go totally off grid subject to me getting planning for the building.

 

I was quoted £140k to get electric to site so didn't even bother asking gas.

 

Electric - solar, wind and genny backup and our lass peddling a bike should all fail

 

Heating - logs, solar with LPG backup

 

Cooking - logs and LPG

 

Hot water - logs, solar, LPG, electric in that order

Dean, my neighbour was once quoted £28k to have gas run up the road and along the lane to him.

He basically said balls to that and they more or less just said oh ok 2.8k then.

 

So don't just believe the first price offered!!

£140K!! - where is the site? top of Ben Nevis?

 

Commando - Solar thermal from Barilla (Lymington, Hampshire) was about £2500 supply only. With the Gledhill Thermal heat store and plumber it was about £5000, but the old heating system was knackered, so it needed changing

 

Its great April - Oct / Nov, but can be a bit redundant in winter as the it will typically only reach 30-40 deg C and the tank already has that heat left from the wood burner the day before - thus it wont take the heat from the roof. A twin tank system, or heat exchanger, can solve this I believe?

 

Not sure I would use a small heat store (ours is a Gledhill 250 ltrs) if I did it again - it looks cheaper to use a standard tank and heat exchanger units, which are maintenance free and allow lots of connections (i.e. solar thermal, oil, gas, wood etc). Something like that...

Craig,

Link please?

I will however cost the 3 ph connection, if only to "add value" to our property for future generations ( mind, a trifle wistfully at the moment)

i'll ask, as I remember it was a 3ph gen to run the farm that also automatically heated the thermal store for dhw and ufh and charged a battery bank/inverter for the house, with the option to add in both solars, around 40k from a firm in Lincolnshire.
