Oil Boiler commissioning and servicing

Hebridean Heating Commission and Service oil boilers to achieve the correct combustion. Each oil boiler requires to be set up to the correct Co2 to prevent the boiler using too much or not enough fuel. The air to fuel ratio should be kept slightly lean to ensure that complete combustion occurs.

It’s important that new boiler installations are commissioned. New boiler’s are manufactured set lean and is mandatory to commission to the correct manufactory instructions. If not, the oil boiler burner will continue to take in too much air, which will inevitably create cracks amongst the baffle plates (The baffle plates store heat inside the chamber of the boiler)

Condensing boilers are significantly more efficient than non condensing boilers. The heat exchanger in a condensing boiler is designed to extract maximum heat from the flue gases. Which reduces the temperature of the flue gases to below the dew point of the flue gases, causing water vapour to condense on the surfaces of the heat exchanger.

The condensate trap isolates the discharge which builds up in the primary heating/cooling system. This is caused by the fluctuations in the pressure and temperature within those systems. A discharge pipe joined to the condensate trap allows any held water passage out of the property and into a drain.

During a boiler service, we inspect your oil tank for water. Whilst working in the Hebrides I have found it common to find an inch or so of water in oil tanks. The two most common causes are rainwater, horizontal rainwater in our case. Rainwater will find it’s way into a tank that’s had a lack of maintenance, faulty or corroded seals, cracks, damaged vents. 

The second is condensation. Condensation is the most likely cause. As moist air cools down inside the tank it will inevitably cause a high humidity in the air to form water droplets. These droplets form on the inner walls of the tank, and as water is heavier and denser than most fuels, a layer of water eventually settles on the bottom of the tank. The water accumulates over time and results in exiting the fuel outlet pipe causing damage to your oil burner.
