We tested the new heater over night, and we were aware of it on occasion as it switched on and off in response to the fall and rise of the temperature. (Note to self - It works, so we can trust it when we're not here, too.) (Pass note to Grace.)
There's something of an enigma about the heater, though, and I need to work it out. The marina operates a "Winter Watch" scheme, in which registered boats have their electricity meters read regularly by marina staff, and topped up if they get low. Kantara's registered on the scheme. On 1st January, I installed the heater, set it to its 5° setting, and left it. The meter said there was £11 of electricity left. Not able to top it up myself at the time, I rang the office a few days later, and explained that Kantara was now using more electricity than before, and please would they top it up for me.
Today, I checked the meter. It read £17. I was told in the office that £20 had been added to the meter on the day I phoned. I did the sums. They weren't difficult. They showed that Kantara had used £11+£20-£17 of electricity on 13 days. £14 in 13 days! The heater only consumes 500 watts maximum, and only switches on when the temperature drops below 5°. Something's not right, and I'm hoping that it's with what the office told me they had added to the meter! I'll discuss it with them tomorrow.
It snowed early this morning,
