just one example; there are many.
Available as either oil or gas-fired.
Or even wood as the fuel.
An "indirect" system uses a coil in the boiler
to transfer heat to a remote "tank" for domestic
A "tankless" system uses the coil to directly produce
the hot water (no storage).
Can be built either as a steam heating system or
as "Hydronic" (circulating hot water thru rads or
fin-tube convectors or even radiant).
What I really need is a small unit for an over the garage apartment to
provide heat and enough water for a quick shower and to do the dishes.
If you could spare a few minutes to check if the unit below might work
I'd be very greatful.
The other thing I need to decide is under floor heating or baseboard
heaters? Right now the underside of the floor is open so it would be
easy to staple up the plastic pipe but I'm a little concerned as to
how well this system would work.
Thanks again for any advice
For a small area, a gas-fired hot water heater can be employed.
For example, a 40 Gallon, self-contained water heater. The
common heater is vented thru a chimney but if none is available
a "power vent" heater can exhaust thru the wall.
If electric rates are low, an electrically-heated tank could be
used as well.
The heated water is circulated on demand by a small circulating pump.
The same water is also available at the tap under pressure.
As long as care is taken to use materials suitable for potable
water, there is no objection to this arrangement.
