30+ year old original boiler was removed and new boiler was fitted in an outhouse connected to the property. The old open vented system was converted to a sealed system and pipework adjusted and extended to the new boiler position. The system was thoroughly flushed and system water was tested using the Adey pro check where the inhibitor, corrosion and pH levels were checked and all passed - this ensures the new boiler has the best start possible. Naviens own smart thermostat was installed and Priority Domestic Hot Water (PDHW) was set up. All exposed pipework was insulated reducing heat loss and on completion, the flow temperature and flow rate was set to ensure the boiler was condensing for as long as possible, further improving its efficiency.
This is usually the result of a faulty actuator on a motorised valve.
This is normally a result of the circulation pump or a motorised valve having failed.
This is usually caused by air being trapped in your radiator. Using a suitable radiator ‘airing key’, you should be able to release the trapped air through the ‘bleed point’ at the top of your radiator.
Your main oil shut off valve can usually be found at the bottom outlet of your fuel tank. The valve will have either a wheel type handle (clockwise to close) or a lever handle (quarter push to close).
Annual servicing can increase your boiler efficiency, reduce emissions and ensure its safe operation. Studies have found that with just a 3mm layer of soot, your boiler efficiency can be reduced by more than 8%.
Your boiler restart button, also referred to as ‘lock out’, is located on your boiler burner unit. Usually, the burner unit front door cover will need to be removed to gain access to the control box reset (when ‘tripped’ the button is normally illuminated). To initiate a start-up, simply push the reset button – always […]
The majority of modern boilers are installed as sealed systems with no header tank to automatically top up the system with water. The system pressure gauge, located either on the front of the boiler or on a nearby pressure vessel, will normally indicate 1 Bar when the system is cold. If your gauge is showing […]
Have you checked your Fuel level? If there is plenty of oil in tank – call us and we can arrange someone to callout. If oil level is low or tank has ran dry the boiler will Lockout. Buy Heating Oil.
