Review on Sengoku HeatMate MH G420A Graphite Champagne by Jenny Mendez

I bought two of these heaters from my local farm shop in early 2020. They were at the checkout for 50.00. I was interested in low power. I have propane heating for my house (in the country) and solar panels to help offset my electric bills. My electric utility switched me to pay-on-demand after installing solar panels (highest electricity usage at any point in the billing period), so I needed low-effort/watt heating. They worked so well that my stove wouldn't keep turning on (propane is very expensive). Now I have four, which together only use what a normal radiant heater would use on its own. I have a 2200 square foot semi-detached home with an open floor plan. They operate remarkably far apart, operating almost 24 hours a day, 7 days a week. It was 11pm last night and my stove came on maybe twice. I've only had the two newly ordered ones with me for a few days, but the other two were used last season in combination with a stronger heater. I was so impressed that I replaced the other two high wattage heaters with two more Sengoku heaters.
