Ideal Logic Combi ESP1 30 Boiler Details
The Ideal Logic Combi ESP1 30 arrives fully assembled with a DHW plate heat exchanger, diverter valve, circulating pump, pressure gauge, safety valve and CH expansion vessel already fitted. It also includes an automatic bypass, boiler frost protection and a daily exercise of the pump and diverter valve. The casing is white-painted mild steel with a white polymer front panel. All pipework runs downwards from the boiler, and the data plate showing the model and serial number sits on the underside of the casing.
The user control panel has three knobs: one for DHW temperature, one for CH temperature and one for mode. The mode knob selects Boiler Off, Summer (hot water only) or Winter (heating and hot water, with hot water taking priority). A back-lit LCD shows status codes and a flame symbol while the burner is lit. A marked economy setting on the CH knob keeps flow temperatures low enough for the boiler to condense. According to Ideal, turning the room thermostat down by 1°C can cut gas use by up to 10%.
Frost protection works in every mode as long as the mains power stays on. If the water inside the boiler drops below 5°C, the boiler runs until it reaches 19°C. To stop the pump seizing, it also runs briefly once every 24 hours, whether or not there is any heating demand. After the burner shuts off, the fan keeps running for a short time. Do not cut this overrun short by switching off the mains.
Engineers can open Installer Mode by holding FUNCTION and RESTART together for more than five seconds. It first shows the last three faults, then gives access to these functions: SL (minimum rate), SH (maximum rate), VF (a 5-minute venting cycle), dU (diverter valve to mid-position), P1 or P7 (minimum pump speed of 100% or 70%) and SE (service timer). The maximum and minimum rate modes each run for 10 minutes for combustion testing. A CO/CO2 ratio below 0.004 is a pass.
The built-in filling loop connects between the DHW inlet valve and the CH return valve, so you can top up the system without a separate hose. The 75 mm siphonic condensate trap lowers the risk of freezing. If the condensate pipe does freeze, the boiler makes a gurgling noise and then locks out on L2. Thaw the pipe with warm water or a heat pack, never boiling water. Internal condensate pipework needs an internal diameter of at least 19 mm, and external runs need at least 30 mm.
The boiler can be controlled by a 230 V room thermostat or timer, an OpenTherm device, or an optional outside sensor for weather compensation. With weather compensation fitted, the CH knob sets the room temperature instead of the flow temperature. There is a wide range of flue options: telescopic and non-telescopic terminals, vertical kits, high-level outlets, balcony and soffit kits, and flues with aluminium inner ducts for high-rise buildings. Every extended flue must fall 1.5° back towards the boiler.
The boiler should be serviced at least once a year by a Gas Safe Registered Engineer. The service includes cleaning the burner, heat exchanger, siphon and DHW filter. Ideal recommends specific inhibitors because the heat exchanger is aluminium, and artificially softened water is not allowed. A scale reducer is recommended where water hardness is above 200 ppm.
