Hot Water & Heating

Hot Water Storage includes, Thermal Stores, Buffer Tanks, Single & Multi-coil cylinders

Buffer Tanks

Buffer tanks and thermal stores are used to store heated water. The source of this heat can be from one or a combination of the following. A conventional oil or gas boiler, heat pump, thermal hot water solar system, or even surplus electricity from a wind turbine or photovoltaic array powering an immersion heater.

Buffer tanks are very useful to system designer of a low energy heating system. They allow them to store energy from different sources to be used later to heat hot water or the buildings underfloor or conventional heating system. They also help to reduce boiler or heat pump cycling, and maintain adequate flow rates through appliances, all of which are critical in maximizing efficiencies. eco hometec freestanding buffer tanks are available in capacities form 200 to 700 litres.

A buffer tank is recommended to ensure trouble-free heat pump operation. It acts as a bridge during electricity supply shutdown periods and as separator between the volume flow in the heat pump and that in heating circuits.

We can supply buffer tanks fitted with a heat exchanger for boosting the DHW with solar energy. These are used in our designs were solar water heating is used to heat the central heating system, typically a low temperature ecotherm underfloor heating system.

Duotank Stainless Steel Unvented Hot Water Cylinders

130, 160, 210, 240, 300 and 500 Litre High Performance Stainless Steel Hot Water Cylinders. Traditional coil-based cylinders are often hard-pressed to keep up with demand. Duotank technology represents a significant advance in the science of hot water storage, so much so that, in virtually every situation encountered, the coil-based cylinder is completely out-classed.

The domestic hot water is heated and stored in a stainless steel vessel, which is immersed within a primary tank - a principal known as a tank within a tank. This method provides not only exceptional efficiency, but ensures thorough and even heating of domestic hot water.

The eco hometec Duotank range of high performance hot water tanks are ideally suited for providing volume hot water for a variety of domestic and commercial applications. The principal of design and the quality and type of material used, creates a product, which offers not only exceptional performance, but also with the important advantage of long-term reliability, internal hygiene and virtually maintenance free operation. The Duotank range of hot water tanks are listed in the Water Byelaws Scheme's Water Fittings and Materials Directory and are approved for installation.

The incredible heating surface area of the Duotank stainless steel cylinder from eco hometec ensures fast and efficient hot water recovery times.

eco hometec Solarcyl Twin Coil Stainless Steel Hot Water Cylinders

Solar thermal water heating is a very simple concept. The sun's energy is absorbed into the solar collector on the roof of the property. The collected solar energy heats a water/glycol mix that is pumped between the collector and the solar heating coil in the eco hometec Solarcyl, which heats the water contained in the cylinder.

The system is normally controlled by a programmable solar controller that simultaneously measures the temperature differential between the cylinder and the collector. Sensor points are provided in the eco hometec Solarcyl to allow this measurement. A target temperature is set on the controller which the solar system will aim to achieve provided solar energy is available. During the summer months, up to 100% of hot water can be produced by solar energy. Even in winter, solar can provide a pre-heat to the water which can reduce traditional energy consumption by up to 30%. Over a full year, up to 70% of hot water can be generated using solar energy. At certain times the energy available from the sun will be insufficient to fully heat the cylinder to the desired temperature.

In these instances an auxiliary power source will be required to maintain the desired temperature of the cylinder. eco hometec offers two types of Solarcyl. The twincoil has an upper auxiliary heating coil for connection to a boiler. The solar direct has an additional immersion heater above the solar coil and is designed for properties with electric heating.

eco hometec Unvented Hot Water Cylinders

The eco hometec Solarcyl is a stainless steel unvented hot water cylinder which has a 25 year guarantee.

Unvented cylinders are connected and supplied directly from the cold water mains supply, resulting in hot and cold water being delivered to all outlets within the dwelling at mains pressure. Fast filling baths and power showers are a reality. Feed and expansion tanks associated with a conventional cylinder and tank installation are no longer required.

eco hometec unvented cylinders offer high performance water heating and hot water delivery flow rates of up to 55 litres per minute. The very large surface area of the solar heating coil means that the maximum heating advantage can be achieved from the solar system.

Unvented cylinders are now commonplace in the UK and are taking over from traditional gravity fed (vented) cylinders as the product of choice for many installers in both new build properties and retro-fit units in existing properties.
