Fanar Collings BA HONS

On Line Plumbing and Heating Ltd. specialise in domestic plumbing and heating. We offer a complete service to keep the upheaval in your home to a minimum. Most of our work is by recommendations from existing clients.

After running a successful business in Devon, Adam Collings moved his business to London and set up On Line Plumbing & Heating Ltd with Fanar in 1994. It is a family run business with Adam doing the plumbing and heating work, while you will find Fanar at the end of the telephone or email who makes the appointments for Adam. Celebrating over 30 years in business.

Adam has recently changed his working practices to lighten his workload. We are therefore only working quite close to home and rarely even in Fulham due to the traffic issues in crossing the bridges.

Tips

If you're having heating problems, here are a few things to look out for:

On a combination boiler
(Instant hot water with no hot water tank)
- Check room stat is not turned down and check the timer is on.
- Most combination boilers will lock out when the water pressure in the system is below 0.05 bar. The boiler can be re-pressurised using the filling loop which can be part of the boiler or a silver braided hose on the boiler pipe work. It will need to be re-pressurised to 1-1.5 bar. Once the correct pressure is achieved, the filling loop must be turned off.
- If you have air in the top of a radiator, you can vent it but you muster-pressurise the boiler to 1.5 bar as explained above.
- If an RF (radio frequency) room stat is fitted, check the batteries in the room stat do not need replacing.
- After a power cut the RF room stat may need rebinding with the base unit, refer to manual.
- The boiler may need resetting, reset button varies on each boiler, refer to manual.
On a standard system
(Fully pumped with cylinder and tanks)
- If only hot water or heating does not work, it is more than likely a jammed zone valve. You can temporarily override the zone valve to stay permanently on. Zone valves are generally found in the cylinder cupboard, near the boiler or the boiler pump, they can be silver boxes, marked Honeywell. A lever on the end of the silver box can be lightly moved and lifted into lock position. DO NOT remove the boiler cover other than the easy to open hatch as you will not be able to fix anything and you may make matters worse.
- Follow instruction for re-pressurising the system as above if you have vented a radiator and the system is pressurised.
- If no hot water, turn on the immersion on the hot water cylinder temporarily
