Gravity and mains pressure hot water from the same cylinder

Mains pressure hot water systems are extremely popular these days, but they can prove to be a significant investment. The beauty of mains pressure systems is the performance you can expect to achieve (providing you have sufficient pressure and flow rate in the cold water main - see note below).

It's one thing to desire, it's another to be in a position to spend the money and prepared for the upheaval.

The rest of your household hot water plumbing continues to operate under gravity conditions exactly as it did before. This of course does away with the need to install a shower booster pump to increase the performance of a typically low pressure gravity hot water supply to your shower. In such a scenario it would of course be prudent to provide a mains pressure cold feed to your shower valve also - thus providing fairly well balanced supplies. (Shower equipment connected to a mains pressure feed should be of the 'thermostatic' type.)

(Note: The performance of a mains pressure system is entirely dependant on the pressure and flow of the incoming cold water main and is subject to the normal fluctuations in pressure, temperature and/or flow. Once installed a mains pressure supply cannot be boosted if you are subsequently unhappy with performance. To do so is in contravention of Water Bye Laws. With ShowerCyl the same rules apply to the mains pressure coil and associated output, but you are at liberty to continue doing anything you wish with the stored gravity hot and cold water in your system. Interestingly this leaves you the option of reverting back to your gravity stored water if for any reason you find yourself unhappy with performance which would then enable you to install a pump. For this reason, if no other, it might be considered wise to request a shower take-off when ordering your cylinder.)

The benefits and savings

1. Mains pressure hot water from your gravity system from a dedicated shower take-off without comprehensive re-plumbing of your house.

2. No need to worry about G3 Building Regulations or an annual service on the cylinder.

3. Save money on the cost of A) a shower booster pump (no need to buy a pump), B) a Surrey Flange for your cylinder (a necessary component if you install a booster pump), and C) a larger header tank for the loft (often required to cope with the higher demand for water created by the pump).

Please be advised, the ShowerCyl cylinder can produce enough mains pressure hot water for you to shower. If you like the principle of the system but would like to supply the entire house by this method you should look at the TORRENT range of cylinders on this website. The ShowerCyl by comparison has a limited output to the Torrent and is designed to cope with the demands of a typical shower.

Combination ShowerCyl Hot Water Cylinders

An excellent application for the ShowerCyl cylinder is where a lack of loft space demands you use a combination cylinder (a cylinder with a built-in header tank). It is often observed that combination cylinders provide very poor pressure (because the head of water is so low) and that it is impossible to get a decent shower because of this.

A remedy one might attempt is to install a shower booster pump. This however is not advisable because the header section of the cylinder will empty so quickly you run the risk of the system going dry (not a good idea and not particularly practical).

It is possible with the ShowerCyl cylinder to provide a dedicated mains pressure hot water feed straight from the cylinder whilst leaving the rest of the system in normal gravity mode. (just a couple of things to note, ensure you have sufficient mains pressure and room enough for a cylinder of a suitable size to make this viable.)

Regulations, installation and servicing

Mains pressure hot water systems that contain in excess of 15 litres of hot water under pressure are subject to Building Regulations (Section G3). Because the quantity of mains pressure hot water in the ShowerCyl system is below the 15 litre threshold at any given moment a cylinder of this nature does not present any issues under Building Regulations, it therefore does not require specialist installer, it does not require commissioning and certification and does not require an annual service. For these reasons it is permissible and entirely reasonable for any competent person to install one.
