my DD moved in to an old farm house that was built in 1929, and even tho it had a room for the bathroom, no plumbing was ever put in to the house, it did have a kitchen sink but a bucket was under the sink and (it looked like at one time it may have had a pump that was fed by an old cistern), but all of that is no longer usable, the well is nearly gone, (and a new one is in the 15,000 range in our area), so they pump about 10 gallons out of the well (about all the well will pump at one time) and take to the house and out side the house there is a fill bucket, they can put the water into, and that will fill the tanks in the basement, there is a hand pump at the kitchen sink and in the bath area, we put a coil in a wood stove, and that will heat the water, in an old how water heater tank, (under each hand pump is a two way valve), and by selecting the hot or the cold pipe you can either pump hot water or cold water, to fill the tub they put an extension on the bath room pump and it extends it over to the tub, (there is no toilet they use an out house), the well will not support a flush toilet,
they use a wringer washer for there clothes,
they even use a wood cookstove I would have considered using the coil in the cook stove but it would not have gravity feed the heat circulation,
the heat coil has safety T&P valves there is a tempering valve on the hot out, and there is a heat dump, if the tank gets above 160F I took a new automotive thermostat and made a housing so if it gets up to open the thermostat, it will start to circulate though the old base board heat coils dumping the excess heat, it all works well, and the shut off valves are drain out valves to the heat coil and to the hot water tank, so if the valve is shut it is venting as well to atmosphere, thus 0 pressure in the tank and the only pressure that can built is the water in the three supply tanks, so the way it is set up one can not trap water in the heating systems and make a steam bomb, the wood stove is on the right side of the water heater tank, on the other side of the wall, the heat coil is a 3/4 pieces of steel pipe that is bent into a "U" shape, and the ends stick through the back of the stove.
