We are looking at a straw powered boiler 995kw to provide heat for grain drying, workshops and a house on site. The above would all be in the same yard. However there’s a cottage the business owns that’s 1500ft away from where the boiler would sit. Is it viable to think of connecting it on. The requirement of the house is about 60,000 kWh from a loose verbal check so would need surveying properly but it just seems silly not connecting it if it’s viable but what size pipe would be needed for a 1500ft run?
