‍JANSTAR wall-mounted warm air boiler:

‍

‍The JANSTAR warm air boiler from Johnson and Starley is particularly notable because it is wall-mounted - the only wall-mounted warm air boiler I can think of. 

‍

‍However I don’t know a great deal about it having only ever encountered one so far out in the real world. It is particularly notable for being room sealed and fan-flued with a dual concentric flue system, rather like the Johnson and Starley Economaire, and for using the System-ET control system. This all means it is unlikely to be tricky to repair or service, subject to these two provisos. 1) Good access to the boiler will still be required, and installers have a habit of fitting wall-mounted boilers in awkward places. 2) I don’t have a stock of parts in the van for this specific boiler so two visits may well be necessary. One to diagnose the fault and order parts, then a second to fit them and and complete the repair.

‍

‍The boiler uses the same 230Vac HI-SPEC system of heating control with a “Thermista-stat” room thermostat as all the HI-SPEC and Economaire models, but appears not to be available with the HIJAN water heater accessory, optional with most other Johnson and Starley warm air heaters.
