Oil Boilers

Oil heaters have long been used to heat swimming pool water. A few are available that have the pool water flowing directly through them and operate in a manner similar to the gas heater. In the main they are standard domestic or commercial boilers which are connected to the pool water via a heat exchanger.

In this case the oil heater can either be the main house boiler with the heat exchanger added to the system in a manner similar to an additional radiator; or as a stand-alone boiler. In the latter case the boiler will need to be fully installed with either a header tank or expansion vessel and connected to the heat exchanger with a set of primary flow and return pipes.

As with the gas boiler the flue and ventilation requirements are critical. Care must be taken when sitting the boiler to ensure that flues do not terminate close to windows, to boundaries, etc. Additionally stand-alone boilers will require connection to an oil supply whether existing or a dedicated tank.
