Solarventi sales process was so straight forward. The gentlemen were able to confirm over the phone from photos and internet bird's eye photos of our house.
No site visit was necessary before arrival for installation. Saves precious resources. Saves me time.
Compare this with SolarEssence from Thetford.
They cold call and on agreement send round a "marketing executive" salesperson who want to visit and take 2 hours of your time without adding to your day.
Retails at 12,000 he says, when I dismissed his price of over 6,000 out of hand.
The amount of solar radiation in Dec. is less that 1 KWh per m2 per day on average in the UK. Therefore the idea that you can "heat your house" or provide more than 70% of your hot water requirements annually without some large m2 of vacuum solar tubes and some very efficient heat storage is just fantasy.
Even if gas rose to 10 times it current price their offering would not have saved me over 6,000 in it's lifetime. And there are much more economic, efficient, ways of being "green".
e.g. Biogas, or wood fuels, or electric efficient heat pumps.
The solarventi is an exception in my view. It does more than just add hot air. It has freshened our bathroom upstairs less over the summer months with the sun so high. But it has been more active as August has passed and the sun's angle of incidence on the panel has increased. Remember the panel is close to vertical.
The dehumidifying action increases too.
I was able to switch off the central heating earlier this year than previous years and I anticipate the central heating will come on later this autumn. I am conscious that the solarventi is part of the reason for this. It's 17 degrees outside this morning but bright sunshine. The central heating might have kicked-in over night (but it's not switched on). But the solarventi was purring away with the early morning sun.
We visited a friend last week, it's mid-August, who had windows on trickle vent/closed upstairs and the mugginess in the bathroom was a reminder where we would have been without the solarventi.
