Integral to any central heating system a hot water cylinder is the go between for many of today’s sustainable technologies. The cylinder itself comes in different formats and works with solar power, normal gas and electricity supply, operates as a stand alone immersion heater or boiler and also works well with air and ground source heat pumps.

What Are The Different Types Of Hot Water Cylinders And How Do They Work?

There are several types of hot water cylinders. The latest models can connect with solar panels and solar collectors to enable transference of heat to the coils surrounding a solar cylinder. This then stores the liquid for redistribution directly or heats the water further to maintain the correct temperatures as requested by your central heating system. These are available in both direct and indirect units and will either have its own energy supply or feed in from an existing gas, oil or electric boiler.

The new age hot water cylinders which don’t deal directly with solar power and instead act as primary or back up water tanks for boilers have been re-engineered with the latest materials, from HCFC free insulation, through to better use of copper and stainless steel with the majority of parts fully recyclable. They utilise insulation combined with heat generating circuits to maintain and adequately heated water supply for both radiators, underfloor heating and hot water use.

What Are The Benefits Of Hot Water Cylinders

Hot water cylinders are not a new invention, however due to the demands of a carbon free society coupled with the need to save energy. Better mixes of materials ensure heat is contained longer, redistributed better and with solar energy creating electricity, enabling all sources to be contained and used for longer periods of time, saved for when needed.

  • Recovery times can be 20% more efficient
  • Fully recyclable units can now be bought, many utilising insulation from sustainable sources
  • Can provide domestic hot water and with immersion option heat any water heated from solar power to adequate temperatures

What Are The Costs Of Hot Water Cylinders And How Much Can Be Saved Or Earned?

Energy savings can be found from its ability to retain heat for longer periods thanks to better insulation. The costs of an additional cylinder whether for solar or normal water storage can range from a few hundred pounds to a few thousands. The former and investment easily recovered within a year of use when combined with other renewable source installs.

Is There Much Maintenance With Cylinders And Are There Any Other Issues?

General cleaning and emptying of deposits from the water boiled, akin to scale on a kettle will ensure the longevity of your hot water cylinder. Aside from that, they are not complicated pieces of equipment. If you include the unit in any annual or two to three year visit by a certified engineer, you won’t be mocked for playing it safe. Always read the manual to ensure proper cleaning and parts maintenance.

Are Cylinders The Right Renewable For You And Your Home Or Business?

Space is usually the main concern for those seeking out renewable sources. A hot water cylinder can be twice the size of a normal immersion heater, though they are becoming more light weight. If you are switching to solar power panels or solar collectors then the system will benefit greatly from the use of a solar cylinder. As will any ground or air source heat pump system.
