Ideal Solar Thermal

The Technology

Solar thermal hot water systems offer a simple and affordable solution for a wide variety of new build and retro fit applications. Often chosen for their hard wearing and performance benefits, modern Solar thermal technology can deliver significant hot water results even in the often dull UK climate, which means even on a cloudy day, solar gain can still be made.

Ideal technology provides solar thermal solutions in both flate plate or evacuated tube format collectors.

The Ideal flat plate technology is available in on-roof panel format, the TS8000, and in-roof format, the TS8001. Both models are manufactured on dedicated robotic lines and feature aluminium absorbers with selective surface coating for optimum heat collection and therefore efficiency.

Evacuated tubes absorb solar energy converting it into heat for use in water heating. Each evacuated tube consists of two glass tubes made from extremely strong borosilicate glass. The outer tube is transparent allowing light rays to pass through with minimal reflection. The inner tube is coated with a special selective coating (Al-N/Al) which features excellent solar radiation absorption and minimal reflection properties. The top of the two tubes are fused together and the air contained in the space between the two layers of glass is pumped out while exposing the tube to high temperatures.

Delivering an average of up to 60% of the homes annual domestic hot water, Ideal solar thermal offers pressurized systems which collect solar radiation from the sun and transfers it into a heat absorbent fluid. The fluid is then pumped into a twin coil cylinder to heat the homes domestic hot water supply. This system works in conjunction with a system or heat only boiler which supplements the system when required.

Quick and simple to install, Ideal flatplate collectors can be mounted in-roof or on-roof with the minimum of fuss, while solar evacuated tubes can be quickly installed on a roof. For flat roof installations a easy-assemble A-frame can be utilized in both options. Available in a choice of easy to specify packs, Ideal solar thermal offers a hassle free solar thermal solution, designed for a wide variety.

How the solar thermal system works

Ideal solar system

A solar thermal system is made up of solar collector(s), a pump station, a twin coil cylinder, a solar controller and a boiler.

  1. Solar panels are located on the roof of the property which collect solar radiation, heating the solar fluid contained inside.
  2. When the fluid has reached the desired temperature, the pump station will begin to draw the hot fluid down and into the twin coil cylinder
  3. The hot fluid enters the twin coil cylinder via the bottom coil and heats the water held inside. A sensor within the cylinder monitors the temperature of the water as it increases. The hot water is then ready for use within the home.
  4. If the water within the cylinder doesn't reach 60°C, or the set temperature, the boiler will fire up to supplement the system.

Ideal flat plate collectors

TS8000 and TS8001

The lightweight flat plate collector is manufactured on its own robotic line.

The number of individual components has been kept to a minimum for this product concept. A specifically developed glue is the only joining technique used at the flat plate collector.

The collectors come with an aluminium absorber. Equipped with a modular mounting system, the collectors can be used for both flat-roof and roof-mounted installations.

Ideal evacuated tube collectors

Solar evacuated collectors 15 & 20 tube

The collector manifold is manufactured from copper and conducts heat transferred by heat pipe technology to the heat transfer fluid, which is pumped through the manifold and to the thermal store.

This process is repeated whenever the collector temperature is more than eight degrees hotter than the thermal store until the desired temperature is achieved.

The collector manifold is designed to manage high pressure and large water consumption systems, making the Ideal evacuated tube a good all round collector.

Twin coil cylinder

A hot water cylinder with two coils should be used in an Ideal solar system. The lower coil connects to the solar circuit, whilst the upper coil connects to the normal boiler circuit.

The cylinder capability can be determined from household size and number of panels.

Roof types and installation

A range of mounting systems from Ideal ensure the collectors can be installed in the most appropriate manner for the property you are working with.

Our solar packs come complete with all the necessary mountings needed for a pitched on-roof installation.

For neater (often new build) installations, an in-roof (inset) mounting kit can be used to achieve a subtle and stylish look. For flat roof installations, a simple A-frame kit is available, providing a quick installation with the minimum of fuss.
