Conventional Boilers

Conventional Boilers

Conventional systems have proved an effective way to provide vast quantities of hot water to different outlets in the house at the same time. Especially when the average household has an incoming mains water pipe of 15mm diameter, this is not sufficient enough if you want to run the bath and shower at the same time; hence the benefit of stored water.

A Conventional Boiler System

The system works by having two water storage tanks within the loft space of the dwelling. The larger one normally a 50 gallon tank is to supply the hot water cylinder with fresh water to replenish that used when you open the tap. The smaller tank, generally around 4-5 gallons is to supply the heating system. Both tanks are for the purpose of feed and expansion and to maintain the correct levels and pressure in both the hot water and heating systems.

The major benefit of these systems is that if the boiler ever breaks down, the cylinder is usually fitted with a back up immersion heater that allows you to heat the water electrically. The other major benefit is allowing you to have better water flow rates if the incoming mains pipe isn't large enough.

However, this type of system does have drawbacks. A conventional system relies on gravity for the pressure, so if you have a mixer shower running off the tanks the pressure will be very poor. This problem can be rectified by installing a shower pump to increase the pressure.

If you have one of these systems with an old boiler and cylinder, you will undoubtedly be aware of the big problem; when the hot water runs out it takes anywhere between 1-2 hours to re-heat. If you upgrade to a Grade 3 cylinder and condensing boiler the recovery time will drop considerably, in some cases as low as 15 minutes so you will never run out of hot water.
