Optimised design for energy efficient domestic cookers

Apart from a refrigerator, the domestic cooker is the most frequently used appliance in the average home. It is regularly used for several hours at a time and operates at high energy levels, particularly when self cleaning during a pyrolitic cycle. To maximise efficiency, it is essential that the cooker should be insulated to the highest standard to prevent energy wastage through unwanted heat leakage. Using the most thermally efficient insulation products on the market, Promat HPI provide the most cost effective solutions for thermal insulation of domestic cookers and ovens.
The thinnest insulation to maximise cooking capacity
Most electric cookers and ovens conform to a standard overall width specification to comply with the requirements of "built-in" kitchen furniture. By selecting from the most thermally efficient insulation products available, a Promat insulation solution is the thinnest on the market for a given performance level. This means that a cooker insulated with a Promat system can offer the largest internal cooking volume.

Promat meets the difficulties of oven design
Energy efficient oven design is often difficult due to the various connecting items such as fans, lights etc, all of which are potential heat leakage paths. Design of pyrolitic ovens becomes even more difficult due to the high temperature of the automatic cleaning process. A pyrolitic oven has a cleaning cycle that is able to destroy all cooking residues by holding a temperature of around 500 °C (932 °F) for up to 90 minutes. All the oven “dirt” is carbonised leaving only a fine ash. This very high temperature obviously necessitates an improved insulation system to maintain the oven efficiency rating. The most effective way of achieving this insulation performance, while still maintaining the maximum internal oven volume, is by the use of a Promat solution based on MICROTHERM® flexible panels. 

The challenges
  • Thermal management – energy loss control – performance optimisation
  • Minimise heat losses
  • Fast warm up. Maximum efficiency for lowest energy consumption
  • Design for daily operation. No deterioration over working life of appliance
  • Minimum insulation thickness for maximum available cooking capacity

  • Cost effective insulation for most competitive appliance selling price
  • Clean product with easy installation on assembly. Absolutely clean in use
  • Non-combustible
  • Accurately shaped insulation parts for closest fit on assembly

Promat – the optimum cooker insulation solution
Promat can offer insulation solutions that solve all the design difficulties. By incorporating our high performance products into the insulation system to the appliance we can design an "engineered solution" that best meets all design challenges. MICROTHERM® flexible panels, PROMASIL®-1100 board, and PROMAGLAF®-HTK wools  all give fast assembly  and offer the best solution for achieving  the highest energy efficiency ratings in a cooker, often without the need to change the casing or interior design in any way.

Application solutions

Domestic cookers

A modern electric fan assisted cooker is a complex assembly, mainly due to the extra components involved in the sophisticated control capabilities. Light, sensors, and of course the fan itself must all be accommodated by the insulation system. The insulation must fit as tightly as possible around all penetrating items to keep heat leakage to an absolute minimum.

A flexible microporous insulation panel such as MICROTHERM® QUILTED offer the thinnest possible insulation protection, is clean to handle and can be pre-shaped for fast and easy assembly. Each component can be factory shaped with accurate laser cut penetrations for the most precise fit.

PROMASIL®-1100 board is a lightweight calcium silicate board with excellent strength and insulation properties. It can also be shaped precisely and offers the additional benefit of strength for support.

PROMAGLAF®-HTK bio-soluble high temperature wool can be hand shaped during assembly and fitted around the most complex assemblies.
