Plumb Thermals can install all types of hot water cylinders and service and maintain hot water systems. We can design & install a new hot water system, if this is what is required. Past projects have been both large and small scale installations. Sometimes a hot water cylinder is not needed, and it may be more beneficial to have either a single point or multipoint hot water heater. Give us a call if you are not sure which type of hot water system or hot water cylinder your require and talk to an experienced engineer.
Unvented cylinders are covered by Building Regulation Part G, where stored water capacity exceeds 15 litres. and provide hot water at mains pressure to your hot water taps. Plumb Thermals are qualified under G3 to install, modify or service your unvented hot water cylinder.
Unvented Hot Water Cylinder
Unvented cylinders main advantage is the provision of mains pressure hot water throughout the house without the cost of booster pumps nor the requirement for a cold water tank to be sited above the highest hot water outlet, eg an upstairs shower head. By bringing the cold supply from the combination valve you can also ensure a balanced pressure in the hot and cold supply throughout the house.
The disadvantage is the lack of hot water provided if there is an interruption in mains water supply.
Indirect hot water cylinders are heated by your boiler, and normally have an immersion heater as a back up.
Direct hot water cylinders are only heated by the immersion heater.
This may service multiple outlets for the hot water such as a few hand basins or sinks. All that is required is a cold water supply at mains pressure, electricity and drainage.Electric water heaters can also be ideal just for use as a hot water supply to a single hand wash basin, and can be fitted as an undersink or oversink installation.
Buffer cylinders, also called actuators or stores, are used to take up excess heat from a heat source, hold it in a store, to be able to distribute it through the heating system as soon as it is required. It stops the need for the heat source to be continually starting and stopping, thereby making it more efficient and lengthening its lifespan.
