Compare Worcester Bosch Boiler Prices & Expert Reviews in 2021

We all crave for warmth and coziness during the fall and winter days due to low temperatures. It becomes extremely difficult to keep ourselves fresh and active while working or doing our day-to-day activities as it becomes harder to function when our hands and legs become numb in cold. For the purpose of avoiding these issues and making our lives easier in winter days we all need a good heating system to keep us warm. Some people prefer room heaters while others like furnaces and radiators.

Another most popular and effective device to be used during winter season are Boilers. Boilers are a type of central heating system for your houses. It also provides you with warm water for various daily purposes like bathing, washing, cooking etc.

Boilers function by the flow of hot water through the network of pre-installed pipes all along the walls and floors of your houses radiating heat. They use water as its fluid to transfer heat which is an inexpensive and easily available heating source. Rather than directly releasing the heat into the air like the radiator, boilers heat the walls, floors, and roofs of the house which results in keeping it warm from the inside.

There are numerous options in the market to choose from when it comes to heating gadgets or systems. Some people prefer room heaters while others like radiator more. But the question that arises is which one of them works the best to keep us warm? Researchers have suggested that Boilers are the most reliable and efficient system of radiating heat throughout the winter days in our entire houses.

What Do The Experts Have To Say?

“Boilers provide radiant heat, which warms objects in a room. In contrast, a forced air furnace warms the air in a room, which means objects absorb heat more slowly. Some people prefer boilers because they can set their thermostat at a lower temperature and the radiant heat makes the room feel warmer than the actual air temperature. Others say boilers provide more balanced heat throughout the home during the winter months.”

  • Feedback- An efficient wonder

Detail- I had my Worcester Bosch boiler installed as my previous one was showing its age. I am pleased to report that it is one of the best investments I have made. Not only does it do what it’s supposed to, it has reduced my bills to the point that I’ve had folks round wanting to check that I’m not defrauding the energy company 😊. I am no longer concerned about the arrival of the winter and look forward to having many worry free years. And, the portable thermostat is a godsend. You just place it in your coldest area, my hallway, set the temperature and leave the boiler to do the rest. Wonderfully simple but effective, love it 😍


1)      Can I use artificially softened water in the heating circuit with my boiler?

Answer- You can have a water softener in combination with our boiler as it will prevent the hot water circuit from scaling up and losing efficiency.  However, the central heating circuit should be filled with hard water and a chemical inhibitor.  This can be done by using the water softener bypass when filling or topping up.  Alternatively, the filling loop feed can be connected upstream of the water softener.

2)      What can cause an oil boilers burner to lockout?

Answer- A burner lockout could be as a result of no oil or a leak in the pipeline. Another cause of burner lockout is from contaminated oil. This contamination could be from:- Water ingress into the tank from a missing cover, a damaged tank from condensation, sludge, which can occur due to the growth of micro-organisms at the water fuel interface in the tank or rust from a metal oil tank corroding.

Your OFTEC registered installer or oil supplier will be able to assist you with cleaning your tank and flushing through the oil lines.

3)      Do I need an additional room thermostat or timer to use the Wave?

Answer- No, the Wave operates as a room thermostat and has timed programmes for heating and hot water.

4) Where can I get a replacement boiler manual from?

Answer– All of our boiler manuals are available to download via the website. Click on the link below for current boiler models or for discontinued boilers.

5.) What will trigger an alert? –


  • Internet or server outage
  • Boiler Faults
  • Failed Commands (Central Heating ON/Off)

Real-World Use Case: by Karen Wozencroft

It is 10 months since installation. Once the pressure dropped. I didn’t know what to do. I contacted the installer/engineer, and he helped me with text messages to sort out the problem. It was OK since then. If it didn’t give a panic for an old lady like me, I would have given five stars. I am waiting for my first service on Feb 21. I wish changing the thermostat temperature was a bit easier to do.


Nothing says it’s winter louder than getting to use the warmth of radiation and taking hot water showers. To enjoy all these things, we need a good boiler fitting at our houses. When we invest in a boiler which is a luxury product we tend to spend quite an amount which makes it very important to invest in a good one. Which not only works efficiently but also provides quick and effective services to its customers.
