The garage walls are insulated but the uninsulated steel roll up door is only a couple of feet from the water line. It's an attached garage and I heat with wood, exclusively. The capacity of the pressure tank is not great enough to maintain a constant water flow on the cold nights. I havn't had any trouble with the piping after the pessure tank, just with the piping from the shutoff valve to the pressure tank. The pipe reduces to 1' sched 40 pvc above the shutoff valve and above that is a hose bib (at 24' above floor), a brass check valve and a brass valve to drain the system above check valve.Ī booster pump then charges the pressure tank which feeds the house. The water line comes up through the concrete slab in 1½' sched 40 pvc and about 8' above the floor is a plastic ball valve (main shutoff). The outlet of the tank is buried and the filler has been valved so it can be drained and I don't have trouble at that end. My water storage tank is at a higher elevation than the house so it gravity flows to the house. From October to June I have enough snow or cold temp that I don't need refigeration. I have a 400W inverter that I use for cf lighting. I'll probably stay at 12V because of my 12V appliances. But I am upgrading and after the spring breakup I'll have 500W of PV and 440Ah bank. Right now I've got only 250W of PV and a 220A batery bank at 12V. Here is what I've got Power is from PV's mounted on a tower about 50 feet from the house.
