1 battery isn’t enough for a heater
He didn't ask about that, Mr. Doom and Gloom.
But while we're on the subject, I always get an heater Harris battery.
I bet your upset they’ve found a vaccine aren’t you 🤣🤣 what will we have to moan about now
Cold water?
I mean, moaning about a virus that has killed nearly a million and a half people and been so damaging economically isn't the same as moaning about people cleaning with cold water, is it?
The OP didn't even ask about a battery for a heater but here we are talking about batteries for heaters .
I had to go back and check the first post.
I would be sure that most makes of batteries would probably power a pump all day and last a long time if it was kept as close to fully charged as possible.
The O/P mentioned an electric hose reel. That changes things and IMHO probably beats diesel heaters for high demand power requirements.
