We own a big old house with very few radiators. There are about 20 powered by a 70kw oil boiler but we need to install around 40 more radiators. (There are 59 rooms).
We'd hoped to install a biomass boiler & make the oil boiler defunct but as a start up business we're unlikely to get the financing we'd need. Although the government RHI payments would fund all of the biomass fuel, we'd have about £5k a year left over (payable for 20 years but finance repayments would be at least 4 times that). Then we have the cost of radiators (£2.5k) + fitting.
We need some heating in some of the rooms to be able to operate as a business and we have about £15-20k of cash which we had hoped to put towards PV panels, radiators, etc. (PV panels will generate income of around £1.5k per annum).
So our options, I think, if biomass isn't an option initially, are:
Install a second oil boiler (probably 100kw) which would cost around £3k and set this up to power the new radiators. I think oil will cost us around £5k per annum though I hope that after a year we may be in a better position to secure finance. (So we'd be spending £8k on this option).
Or we look at high efficiency electric panel heaters in the rooms we need them in initially (15 rooms) and power these via the PV panels/mains electricity. These seem to cost around £200 each so would cost £3k in total + electricity though I believe we may receive export tariff even if we use the electricity we thought we'd export (5Kw of 10Kw system) as apparently our electricity provider doesn't measure export & we would receive a further 4.77pence on 50% of the total annual generation, or around £247 per year. So possibly there are no energy costs associated with this (it's late at night, I may have got this wrong). This option wouldn't involve having the radiators in place that we'd need for the biomass, but would cost less potentially in year one.
Are there any other options and does the above make sense as an analysis? Any (polite) comments gratefully received.
