Oil system boiler installation costs can vary enormously, but you can compare prices by getting a fixed-price quote from different local and national installers.
How will I know if this Boiler is Suitable for My Home?
Oil system boilers can meet the hot water demands of larger homes and require a separate cylinder for storing, meaning they need more space than an oil combi boiler. System boilers, like the LCB700 System, are perfect for homes with more than one bathroom and those that use a lot of hot water at once. If you choose an internal model, it will fit neatly between your kitchen or utility units. But if you don’t have much space to play with, you can opt for an external model.
Before purchasing a new boiler, you must determine the correct size/output for your needs. As a general rule, the more radiators, taps, showers and baths you have, the higher the boiler output you need. If you want to be sure of the correct boiler size for your home, ask a qualified heating engineer for their recommendation.
Is it a High Efficiency Boiler?
The Navien LCB700 System is a highly efficient boiler with an ErP A rating and an efficiency rating of 93%. Furthermore, this system boiler is an Energy Saving Trust endorsed product that comes complete with a high-efficiency circulating pump.
Does this Boiler have a Good Range of Controls and Features?
Yes. The Navien LCB700 System with a lightweight design for easy installation has a full-text driven control panel to help you control heating and hot water temperatures and a stainless steel heat exchanger to prevent corrosion and extend the boiler’s life. It offers revolutionary blue flame technology, which guarantees superior efficiencies and ultra-low NOx emissions. This modern system boiler can even check the weather forecast and adjust itself accordingly to ensure your home maintains a comfortable temperature. The LCB700 System also comes complete with a factory fitted expansion vessel and a combined pressure relief valve and condensate drain.
