Do not accept a COP below 4.5 during the summer.
I promised results from April, so this is a little late. Here they are as a follow up to Going with the flow. We made a change to the temperature at which the electrical heater comes on for our heat pump. The question is: was that worthwhile? Our heat pump gives us the means to […]

Help in the kitchen from a surprising source.
Learning how to make good use of our microwave to reduce our power consumption while cooking has highlighted just what we were missing out on in terms of the unit being an extra pair of hands in the kitchen, almost a sous chef. It should be noted we bought the microwave in 2017, as our […]

Walking in the shadows.
One of the big benefits of having a heat pump that doesn’t provide cool air in the house, is the ability to stand in front of the fans while it rips the heat out of the air to heat our hot water. Yes, dear readers, this is what I have been doing in sunny Ipswich […]
