Rinnai Electric Roofmaster Prestige 250L Hot Water System.
The Rinnai gravity feed ROOFMASTER water heaters are concealed in your roofspace.
The storage cylinder is made from heavy duty copper which makes it extremely reliable and corrosion resistant.
The lower pressure at which they operate puts much less stress on the cylinder and fittings, so everything lasts that much longer.
The Rinnai Roofmaster Prestige comes complete with extra piping enabling it to pre-heat the water with either (or both) solar panels or piping from a combustion stove.
