Do I Have an Open Vent or Sealed Boiler System?

Before diving into the details of regular boilers, it’s important to determine whether your home has an open vent or a sealed system. Open vent systems have a feed and expansion tank in the loft, allowing the cylinder to draw in fresh water from the main supply. Sealed systems, on the other hand, are pressurized and do not require a separate water feed and expansion tank in the loft. This information is crucial in selecting the right type of heat-only boiler for your home.

How Does a Heat-Only Boiler Work?

A heat-only boiler is a traditional central heating that operates by supplying hot water to radiators and a separate cylinder to provide domestic hot water. It works by heating water directly in the heat exchanger and then circulating it through the central heating system to supply hot water. The heat-only boiler is controlled by a programmer and room thermostat, allowing you to set the desired temperature and schedule.

Which Homes Are Most Suited for Heat-Only Boilers?

Heat-only boilers are particularly suited for homes with high hot water demands or multiple bathrooms. They are an excellent choice for properties with existing open vent systems, as they can be easily integrated into the existing infrastructure. If your home has low water pressure or limited space, a heat-only boiler can be the ideal heating solution.

What is the Difference Between a Heat Only and a System Boiler?

One common question homeowners often have is the difference between a heat-only boiler and a system boiler. While both types provide hot water for heating purposes, there are some key distinctions. A heat-only boiler provides heat for the radiators and requires a separate hot water cylinder just for storing water. In contrast, a system boiler supplies higher water pressure for the showers and the cylinder will be fed from the main supply. The heating and hot water components still will be used, and you still need a separate hot water storage cylinder.

Used MML Plumbing for the first time today. Administrator in office was easy to deal with, efficient and helpful. Plumber arrived on time as arranged, fixed the problem and explained what he had done. Quick, tidy and courteous worker. What I also especially liked was that I was given an actual confirmed time when he would arrive and not one of those two or three-hour 'window slots'!

MML Plumbing successfully completed the installation of our heating system in our expansive 8-bedroom residence. The placement of the boiler and cylinder was expertly executed in the basement. They meticulously laid new piping throughout the house to facilitate radiators and hot/cold water faucets. The recent commissioning of the system has resulted in its exceptional functionality. Their impeccable organization and absence of any delays were notable. We definitely plan to engage their services again in the future.

In North London, it can be hard to find a company that you can trust and provide quality work. We called MML Plumbing to install a system boiler and a hot water cylinder. The installation was done in a few days, and now everything is fine. They left the area very clean. I highly recommend them.

⭐⭐⭐⭐⭐ I am thrilled to leave a 5-star review for MML Plumbing's advanced leak detection services. They were able to find a leak that three other plumbers had missed. Their use of thermal imaging and acoustic leak detection tools set them apart from other companies in the area. What impressed me the most was their commitment to resolving the issue without causing unnecessary damage, while other companies suggested tearing apart my ceiling. Their services are not only effective but also affordable.They are a reliable and trustworthy company that goes above and beyond to solve plumbing problems. Thank you, MML Plumbing, for your expertise and exceptional service. I will definitely turn to you for any future plumbing needs. Hollie xxx
