With an output of 30kW, the Ideal Logic Plus Heat is best suited to homes with up to 20 radiators. The H30 is the most powerful of the five regular boilers in the Logic Plus Heat range. However, if your home has fewer radiators and a lesser demand for hot water, then Ideal have the H12 (12kW), H15 (15kW), H18 (18kW) and the H24 (24kW output) that could also be suitable for your home.
Regular boilers are best suited to older properties that have the appropriate existing pipework. However, if you are looking to have a new regular boiler installed, you will need to accommodate for a hot water cylinder and a cold water storage cistern, which is usually installed in the attic. This is because a regular boiler is fed with cold water from the cistern, this water is then heated and stored in a hot water cylinder for when needed. As a result of needing these additional parts, a regular boiler is not suitable for properties with limited space.
