Johnson & Starley O 53-33 _i_ UDC 696 4 PUBLICATION ZZ 301/2 JANUS f ired circulator water heaters A Janus water heater provides generous amounts of hot water for the average family. Economical hot water because: Janus uses gas the low cost fuel; You select the tempשrature you prter; Janus water heating is thermostatically controlled quite independently of your central heating System so gives the same high standard of service and economy both winter and summer. Janus water heaters are manufactured by Johnson & Starley -Europes leading manufacturer of Warm Air Central Heating equipment. You can have a Janus water heater factory-fitted inside your new warm air heater. If you already have a J & S air heater (most models) a Janus can be fitted with no fuss. It will use the same flue and gas supply as your air heater -but operate independently. There is a Janus model to provide hot water service for families who do not have warm air heating. This needs its own flue and gas connection. It is compact and easily installed. Janus water heaters must be connected by two simple pipes to a hot water storage cylinder. We recommend the 'indirect' type of cylinder unless you live in a soft water area where the water authority recommends the use of 'direct' cylinders. Ask your local installer about Janus water heaters - rie'Il be happy to tell you. You will be happy you chose Janus.
