Laars MiniTherm series gas boilers are a great alternative to traditional cast iron boilers - both in new installations and replacements.
They are reliable, affordable and are much lighter than cast iron models thanks to unique hybrid heat exchanger (which is time-proven and backed by a 20-yr warranty) - making them much easier and quicker to install.
A variety of optional installation accessories (NG to LP and altitude conversion kits, outdoor sensor, chimney to power vent conv. kit, low loss header and others) make this boiler a flexible and efficient solution for any hydronic application (baseboards, radiators, radiant heat, etc.)
MiniTherm is capable of replacing practically any cast iron boiler brand - Weil McLain, Pennco, Utica, Dunkirk, Peerless, Crown, Burnham, Lennox and many others.
