Practice what you preach 👌
Over the last month we've had a little side project running.
This week we completed my own home with a 5kW Vaillant aroTHERM plus heat pump and 210L cylinder through the Heat Geek Zero Disrupt system 🔥❄️
With no airing cupboard available, I opted to install the cylinder externally in an insulated shed rather than using the loft space — keeping disruption to an absolute minimum.
✔️ 47°C max flow temperature at -3°C design temperature
✔️ Guaranteed 383% efficiency
✔️ No radiator upgrades required
✔️ Low temperature design done properly
Financially, there’s never been a better time to make the switch:
💷 £7,500 Boiler Upgrade Scheme grant. Soon to be £9,000 for oil and LPG customers
💷 £1,000 Barclays Greener Home Reward
Even as a qualified gas engineer, the numbers now make complete sense to switch
