Heating System Design

To comply with the more prescriptive requirements of the building regulations, central heating systems need to be designed and specified correctly. As a certified member of the Institute of Domestic Heating & Environmental Engineers we have undergone the training and exam requirements to design efficient and effective heating systems.

This includes radiator, boiler and complete pipe sizing throughout a property. In addition we can specify zone controls and offer advice on part L of the building regulations.

Bespoke Controls

Allied Renewable Technologies offers a bespoke software programming service, where we will design and implement heat system controls designed to maximise solar contribution and boiler efficiency of your system. Normally the Siemens LOGO or Mitsubishi Zelio controls are used. But we will also program Siemens S5, S7 and ORMON PLC's.

Feasibility Studies

In carrying out a feasibility study, several design iterations are normally carried out to find the maximum "Net Present Value" of the project. Each iteration is simulated for a 3 year period and the net fuel and costs savings are compared. The program takes into account variables such as fuel energy and CO2 content, daily, monthly usage patterns as well as expected energy inflation figures. The resulting output forms part of the overall feasibility report, and the figures obtained are an important part of the grant application.

Our experience to date has seen that heavy hot water users such as sports clubs, restaurants, hotels, B& B's have the best payback periods. If LPG is being used for heating purposes then the implementation of a solar heating system coupled to a buffer tank can also lead to significant cost savings.

SEI Reheat Grants

The SEI REHEAT grant programme offers commercial applications a 30% grant on the cost of a renewable energy heating installation. The process is more complicated and the timelines are longer than the SEI greener homes scheme, however the overall grant levels are very generous and worth the effort.

Under the ReHeat Deployment programme, grants are available for the deployment of qualifying renewable heating systems in the following categories.

• Boilers fueled by wood chips and/or wood pellets
• Solar thermal systems
• Heat pumps

Installations can be in the commercial, industrial, services and public sectors and also includes community organisations in Ireland.

We offer free advice and can undertake a detailed and costed feasibility study (normally charged at a nominal €800 +VAT) required for the grant application. However the cost of the feasibility study is deducted from the overall project cost.
