We are able to maintain, repair, upgrade and install a wide range of hot water systems. From changing an immersion heater on a hot water cylinder, repairing a combi boiler to installing a large pressurised hot water system.
The basic difference between the high pressure unvented systems and a traditional low pressure vented system is that we no longer require the cold water storage cistern, open vent pipe or cold feed pipe.
Instead, the unvented unit is fed direct from the mains cold water supply via an inlet control group preset to the relevant manufacturers specified pressures. Hot water drawn from the unit is then replenished from the mains supply.
To maximise the benefits of the unvented system, a sealed heating system, if applicable, can also be installed providing the boiler used is compatible.
House Holder Benefits
A thermal store is a large, well insulated hot water cylinder and forms the heart of your home heating and hot water system. A thermal store, stores up heat from a boiler stove, solar panel or other renewable heat sources, that can be used to heat the house and provide hot water whenever it is needed.
The thermal store also lets you easily link up different heat sources. A classic combination is a woodburning boiler stove (winter heating and hot water), solar panels (summer hot water) and a conventional boiler (to provide a back up). Other sources can also include a ground or air source heat pump, an electrical heating element, a wood pellet stove, or even an A.G.A with built a in boiler.
A good thermal store takes in the source energy efficiently and transfers it back out on demand quickly, maintains good stratification (hottest water at the top, coolest water at the bottom) and, most important of all, minimises heat loss.
As an alternative to pressurised systems, a shower pump can be a valuable addition to a traditional vented system.
It is usually hidden out of sight in an airing cupboard, but the humble shower pump is probably the most important item that many people can install in their bathroom.
Changing lifestyles have led to a dramatic increase in the demand for powerful showers in the last 20 years. Time pressures and the sheer luxurious experience provided by a power shower have made them must-have items for more and more British families.
A typical British home contains a vented hot water cylinder with a cold cistern tank in the loft. In many cases, there is simply not enough distance in height between the cylinder and the cold water tank to provide enough pressure for that amazing power shower experience.
Get the installation right and showering will be a consistent and luxurious experience with powerful jets of hot water on demand.
Short of installing an unvented, mains pressure cylinder or a combination boiler, the answer for many is a shower pump. Installing a modern shower pump can raise the water pressure from under 0.3 bar (1.0 bar is the equivalent of 10 metres of head) to up to 3.0 bar. You need a minimum of 0.5 bar of water pressure for the shower to work properly.
As the popularity and accessibility of renewable energy increases, E.M.E Plumbing and Heating will be able to fit and service your solar thermal system.
Solar water heating systems, or 'solar thermal' systems, use free heat from the sun to warm domestic hot water. A conventional boiler or immersion heater can be used to make the water hotter, or to provide hot water when solar energy is unavailable.
The benefits of solar water heating
Hot water throughout the year. The system works all year round, though you'll need to heat the water further with a boiler or immersion heater during the winter months.
Reduced energy bills. Sunlight is free, so once you've paid for the initial installation your hot water costs will be reduced.
Lower carbon footprint. Solar hot water is a green, renewable heating system and can reduce your carbon dioxide emissions.
How do solar water heating systems work?
Solar water heating systems use solar panels, called collectors, fitted to your roof. These collect heat from the sun and use it to heat up water which is stored in a hot water cylinder. A boiler or immersion heater can be used as a back-up to heat the water further to reach the temperature you want.
