Ideal logic ESP1 35kw gas boiler review

The Logic Combi ESP1 35kw combination boiler provides instantaneous hot water and central heating. It features full sequence automatic ignition as well as fan assisted combustion. 

The boiler is highly efficient. Condensate is made from flue gasses and is drained to a point suitable for disposal through a plastic waste pipe located at the bottom of the boiler. At the flue terminal, a condensate plume’ will be also visible.

Why choose the Ideal Logic ESP1 35kw?

Our Logic Combi ESP1 35kw boilers provide optimal SAP and DER performance, making them ideal for new-build compliance. These boilers are lightweight and compact, and Energy Saving Trust approved. You can choose from three outputs of 24, 30, or 35kw. The Logic Combi ESP1 35kw central heat system can be connected with a wide variety of timers for maximum control and peace of your mind. The Ideal Logic Combi ESP 1 includes the following key features:

  • – A clear and easy-to-read pressure gauge that gives you maximum control over your unit
  • Low component count, to ensure reliability.
  • – Fully modulating operation to low outputs
  • – Automatic bypass
  • – Built in easy-to-use filling loop
  • – Simple diverter valve
  • – Flame sensing with two stages to increase reliability
  • – Latest generation Honeywell gas valve
  • Preformed copper tails
  • – Simple to access pre-wired mains leads (2m) for PRV and AAV.
  • – Pre-piping kit
  • Boiler Frost Protection to make sure your boiler is safe during winter months
  • Compatibility with many piping options
  • Optional timers or weather compensation sensors are available to provide maximum control over your boiler.

The boiler is a condensing appliance with high efficiency that will adjust its output to meet heat demand. The heat demand reduces the gas consumption. When the boiler is at its most efficient, it condenses the flue gas water.

Ideal Logic ESP1 35kw weather compensation kit

Weather Compensation is an option that allows you to adjust the thermostat for the central heating system. Turn the knob clockwise for an increase in room temperature. The knob can be turned anticlockwise to reduce room temperature. Once you have reached the desired temperature setting, simply leave the knob in that position. The system will automatically reach the desired room temperature regardless of the weather conditions.

Boiler frost protection

The boiler has frost protection. This protects the boiler in all modes of operation, as long as the power supply to it is always switched on. If the boiler’s water temperature falls below 5oC, frost protection will turn on and the boiler will run to prevent freezing. However, the process does not guarantee that other parts of your system will be protected.
