Readers tips of the month disagree about solar switching devices
Posted by NicoleYouGen on 28 February 2013 at 9:02 am
This month, our readers have given some conflicting tips about solar heater switching devices. Ted from Cornwall installed an Immersun system to route surplus power from the solar panels into the immersion on the cylinder. He is happy and says ‘even in February the panels are heating all the hot water.’
Nigel Surrey, who used his skills from working with financial management systems to design and build a PV Solar Panel Monitoring System, did not feel so warm about Immersun. He says: ‘Beware of solar companies pushing the sale of expensive solar panel immersion heater switching devices such as Immersun. The maximum savings can only be the amount users would spend on hot water heating bills and that is if one heated water from 100% generated power. This would never happen all year round. I rescued my father from falling prey to such tactics would would have taken him 15 years to recoup cost of ¬£1,250 at 100% of heating cost. Quick estimate based on his 1.7kW PV system it would have taken 100 years to cover his normal £12 per month water heating costs.’
This month our readers do seem to agree on two points: check out your installers and insulate.
Solar PV has been positive for Pat Wells, a Norfolk business owner who works from home. The installation has saved his household £165 on electricity bills, on top of FIT payments. His advice for someone considering PV: ‘Asking to see previous installations is a must, and ask to speak to previous customers. Emails, and websites can be faceless, where as a telephone call or visit really helps. You also see what you are buying in action, and see the true results.’
He adds that he is now looking at energy reducing appliances. He says ‘It’s amazing how little time capital expense is recovered by the savings on electricity’.
Keith Searle recently became SuperHome number 150. You might be interested in reading his story of becomming a SuperHome owner. His top tip: Before worrying about the energy source insulate to the highest standards you can manage.
A.WISE from Torfaen installed solar electricity panels using a company recommended by a friend. She says: ‘Always go for a firm that has been recommended, friends are usually a better guide than advertisements or selling agents. Don't be afraid to ask about the things you don't understand, these are the experts and they should be able to answer all your queries.’
Ted has installed solar PV and a heat pump. Last month, he swapped his LPG boiler for an 8.5 kW Ecodan with a cylinder for DHW. Ted says: ‘Take care with your choice of installer and do your research thoroughly’. He adds: ‘Monitor your installations to make sure they're performing as you expect’. And like Keith, he stressed the importance of insulation.
One of the main points this month: research your installers. You can begin by checking out what previous customers say on YouGen).
