Yes, our rainwater supplies the toilet flush and all exterior taps and plant watering. The washing machine is on the mains, but it still means the water bill is halved.We have most of what you have there except the hot water tap and have an air source heat pump instead of the oil boiler.
Rainwater harvesting is great for car washing. We also use it to flush toilets but have disconnected the washing machine from the system as it tended to sludge up. Filter in the tank needs a regular clean due to pigeon poo & dust from the roof. We have also had a pump fail after about 6 or 7 years. Manufacturer discounted a replacement.
Heat recovery ventilation is also great as you have a ventilated house even through winter without opening windows & no condensation - change or clean the filters monthly.
We are all electric and annual electric bill is around £1,150.
Cash back from solar panels & RHI is around £2,750 so we are pocketing £1,600 a year to live in a snug house.
Being new to eco houses, I had to look up RHI....but given the system was built into the house from new by the previous owners we would not qualify.
However, the FIT (Feed in Tarif) has been paying an average of £1k a year to the previous owners. I had to look that up too!.
Just 2 months into ownership and the projections look promising. Time will tell.
Thanks for your input and experience.
