The SOLARvent IQ boiler

The SOLARvent IQ boiler is the latest in wood pellet boilers achieving a constant certificated efficiency of 95% regardless of the demand (load). We are extremely proud of this boiler and believe it is the best on the market. Here is a list of its features and benefits, and please download the technical pdf’s for further explanations and information.

Manufactured in Germany. All parts German or Swiss origin.
Patented 3 way burner, with lambda sensor in the exhaust flue, ensures the exact air/fuel ratio for a perfect burn, resulting in TÜV certificated efficiency of 95%, even at part load of 4kW, setting the Solarvent boiler apart from its competitors.
Boiler carries the Blue angel (Blauer Engel) award; the first worldwide (German) environmental label established in 1978, awarded to products with outstanding environmentally friendly aspects.
Fully automatic, including ignition and self cleaning functions.
2 independent heating circuits controlled by the boiler software, allowing flexible installation options including underfloor heating and radiators, large property zoning, and even 2 houses off 1 boiler.
Hot water circuit controlled at boiler via boiler software.
Solar water heating can be managed by the boiler software; to include a thermal store system if chosen.
Uses weather compensation technology which constantly reads the outside temperature and reacts by modulating the flow temperature to ensure optimum comfort conditions yet ensures minimal energy wastage.
It also eliminates the need for constantly changing the thermostat and programmed heating times.
Manufactured for use in a ‘sealed system’, providing all the safety and interlock features needed including pressure relief valve and overheat thermostats.
Pellet adaption function; In the event of using a different pellet manufacturer, or having a batch of pellets with moisture content higher than expected, possibly due to poor storage, the parameters of the boiler operation can be changed to include more frequent refuels, stable ignition, and, importantly, more frequent cleaning to remove any residue build up.
5yr warranty, 2 year parts warranty, 20 yr life expectancy.
Return temp lifter; Protects the boiler from low return temperatures and the corrosion this can cause.
Extremely easy access for parts replacement and maintenance.
Hardware test for fault finding; This function tests and checks every component from pumps to sensors.
Fire protection; eliminates totally the risk of fire back into the hopper.
Listed on the Energy Technology List; businesses can benefit from energy efficient loans and tax relief because of this listing.

Under floor Heating

Installing an under floor heating system will provide long term benefits. Heating bills will reduce because the required energy input to an under floor heating system is less than a conventional radiator heating system. Underfloor heating uses optimum water temperatures of between 45°C and 55°C compared to 80°C in traditional radiator systems. This means lower CO2 emissions.

Typically, the savings range between 25% and 40%. Under floor heating is the best method of providing heat throughout our homes. We will help you to understand it.

All of our under floor heating products are of the best available quality and they carry guarantees which are not bettered in the market.
The PERT-alu-PERT (PaP) pipe is guaranteed for 70 years and the other under floor system products for 30 years.
Invest in a trouble-free system backed by an industry-leading guarantee. This pipe will become industry-standard in years to come because of its ease-of-use and its truly simple, entirely secure jointing system, all backed by a first class, unmatched guarantee.
Our systems are modular, making them interchangeable and easy to use.

The controls that we offer can be designed and made to suit any application. They can be designed to suit the most complex of operational requirements.

Solar hot water

The Sun is an inexhaustible source of energy. Within just three hours the Sun sends to Earth as much energy as is consumed by the entire population of the planet in one year. Solar water heating systems use this energy from the Sun to heat water.

The technology is well developed and there is a large choice of equipment to integrate solar into almost any heating and hot water system. Please read through our various pages for a greater insight into the technology and to understand how a solar thermal system may work for you.

Flat-Plate Panels

Flat-plate collectors are the most common solar collectors for use in solar water-heating systems in homes and in solar space heating. A flat-plate collector consists of an insulated metal box with a glass or plastic cover (the glazing) and a dark coloured absorber plate. Solar radiation is absorbed by the absorber plate and transferred to a fluid that circulates through the collector in tubes.

Flat-plate collectors heat the circulating fluid to a temperature considerably less than that of the boiling point of water and are best suited to applications where the demand temperature is 30-70°C (86-158°F) and/or for applications that require heat during the winter months.
Flat collectors can be mounted in a variety of ways, depending on the type of building, application, and size of collector. Options include mounting on a roof, in the roof itself, or free-standing.

Evacuated Tubes

An evacuated-tube collector consists of parallel rows of glass tubes connected to a header pipe. The tube works by collecting the suns heat in a copper tube filled with an antifreeze solution. This copper tube protrudes into a water carrying pipe at the head of the evacuated tube and transfers its heat to the water.

These copper tubes can become very hot (up to 200°C) and of the sun’s energy hitting the tube’s surface about 93% is absorbed. They are well-suited to commercial and industrial heating applications.
Evacuated-tube collectors cost, typically, about twice as much as flat plate collectors. However, individual tubes can be easily replaced instead of needing to replace a whole panel. Choosing is a matter of weighing up your requirements and your expectations and matching with your budget.

Which is best?

Flat plate collectors are much cheaper than evacuated tubes. They are also less efficient as they do not capture as much energy as an evacuated tube system. Evacuated tubes collect much more of the suns energy, even on very cold or cloudy days, because of the technology used in the tube and the vacuum in the tube.

What heating system are you using? If you intend to have a boiler heating a hot water cylinder together with solar energy, and your hot water demands are fairly low, then it is unlikely that the extra cost of an evacuated system will make financial sense. On the other hand if the environment is your chief concern and your budget allows, you will definitely gain a higher proportion of your demand by using an evacuated tube system.

So which is best? In truth, the answer could be either. What is more suitable for one project may not be for another. Therefore, each project needs to be assessed against criteria such as available space, budget, catchment area, building position, proposed heating system.

We will help you get the right system for you.
