We have been enjoying our radiator central heating for over a week now. Dale and his team at Senior Plumbing and Heating did the installation. They did a great job, very friendly, kept us informed of what they were doing and kept everything neat and tidy.I wouldn't hesitate to recommend Senior Plumbing and Heating, if you're looking at installing radiators.

Dale from Senior Plumbing and Heating have just finished installing our central heating with 7 radiators for my house and small apartment downstairs. They were very professional, tidy and went the extra mile. Thanks to Dale and his A team. Highly recommended.

Dale did a good job determining the best fit for our system replacement due to CO entering the air supply. Very knowledgeable and pointed out options that will save us money and keep us safe going forward. He also managed a next day installation to get our heat back on.

Vented Cylinders

Vented Hot water cylinders work alongside a cold water storage tank typically situated in the roof. Water from the mains goes into the cold water tank then fed into the hot water cylinder to be heated and distributed to your taps. Vented cylinders have a vent pipe rising from the cylinder itself and into the cold water tank. The purpose of the vent pipe is to release excess pressure and heat in the event of a fault.

Unvented Cylinders

On the other end, Unvented Hot water cylinders are fed cold water directly from the mains which is heated and distributed to your taps. Since the tanks are sealed, they either have a bubble top unit or are integrated with an expansion vessel to hold the pressurized water inside the tank.

Installation Process

Our process begins with a call to arrange a visit to your property. This helps our heating engineers run a proper assessment and even help you identify the best hot water cylinder for your property and boiler. Once we have sourced the cylinder, the installation process begins and it will depend on the project. If you are looking for a replacement, then the process is more straightforward. If the project involves replacing instead of installing a combi boiler with a system or regular boiler, then this might be more complex but either way we will work efficiently on the boiler and the hot water cylinder.


Legally, only a Gas Safe Registered Heating Engineer can install, service or repair a hot water cylinder.
The size of your tank ultimately depends on the size of your house or property. The number of bathrooms is a big factor to consider.
Most cylinders have an original sticker that indicates the capacity, height and diameter of your cylinder.
Complete detachment of the old pump and fitting of the new pump can begin. The new pump can be Grundfos UPS3 Domestic pump or a UP15 – 10BUC5 Bronze Circulator Pump. These pumps are good for radiant heating and solar.
Unless something comes up, at the very most a conversion takes 5 hours to complete.
Your heating engineer can offer to carry it and dispose of it safely.
