Alpha E-TEC plus combi gas boiler: Why choose them?

There is no place with extreme cold weather who don’t need warm water. Boilers are the best way to provide for that need as they are energy efficient, easy to install, and is long-lasting. Agreed there are other ways too that can help you with warm water and serve your purpose well, but we have certain reasons as to why we suggest getting boilers:

1. They are extremely reliable. Packed with fewer mechanical parts, these boilers don’t get damaged easily, unless some mishap occurs. And even if they get damaged, it’s quite easy to identify the damage due to fewer parts. Its main circulator is quite easy to stock and replaces when it is damaged. So, you can rely on them to last longer and get fixed easily if damaged in any way.

2. Boilers are easily affordable. If you compare it to other heating devices, they cover the cost by lasting longer than them. The repair costs are also less. You just need to service them yearly to ensure that they don’t lose their edge, then they can last as long as 20 years. Again, it depends on how you keep it but generally, they can go on for 10 years minimum.

3. Boilers help in easy and uniform heat distribution throughout the house. They radiate heat with the help of heated pipes, which makes it easy to spread it throughout the house. It also helps in heating the rooms fast and keeps them warm for a long period, so you can trust them during winters the most.

When we talk about boilers, there are many types present. However, combi boilers have been the rage for a few years now and for the right reasons too.

a. They are highly efficient. You can now keep your house warm at a relatively less price. These are also environment friendly as compared to traditional boilers.

b. These are small in size. They don’t have any extra parts or components, just the main body of the boiler that will work well after installing it. So, even small houses can install boilers without worrying about their houses being congested. These are also easy to repair/replace in case they get damaged. The best part is you don’t need a conversion kit for using a different fuel in these boilers.

c. As compared to traditional boilers, these are safer and cleaner. They don’t store water, rather supply directly from the mains which lead to less rust and sludge and provide safe and freshwater instantly to the users.

So, if you are thinking about purchasing a combi boiler, here are few things that you should keep in mind:

Buyer’s guide:

  1. Fuel type

It is quite an important thing to consider while purchasing a boiler as this determines your gas bill the most. The best part about combi boilers is you can use two fuels without a combination kit. There are four fuel types people generally use:

  1. Natural gas

Urban households use this fuel the most as it is easily available to them, highly efficient, and also environment friendly. It is injected into the house with the help of a utility man.

  • Propane

This is usually found in suburban areas where there is less or no availability of natural gas. It is stored in a tank which is kept on terrace or underground and is injected via there to the boiler. It has to be filled up from time to time.

  • Fuel oil

This is not too common as people prefer the above two mostly. However, in case those options aren’t accessible, this is used. It has to be loaded manually in the boiler when you need to switch it on. It is quite hard work to have this work well, but in areas where electricity is a rarity, this is a good option.

  • Electric

People who don’t have a huge budget for boilers can opt for an electric one. But ensure that you do have electricity all the time, else you’ll be left in cold in case it goes faulty.

  • Venting options

Venting is an important thing for boilers. The combustion should be let out to not cause any problems with the boiler or suffocation in the house since these gases produced post-combustion is harmful to the people inside. There are three types of venting options available with users:

Chimney, power, and direct venting.

When we talk about chimney vented boilers, there’s a requirement of chimneys in houses for them. If you have it already, this is a good option for boilers. But before you install it, it’s best to have the chimney cleaned properly. This is to ensure there is no hindrance in the combustion as that might cause a fire.

Power vented boilers on the other hand don’t need chimneys. They are direct exhaust boilers and make use of an in-built blower to let the gases out as well as to let fresh air in. The only thing you have to make sure in the case of power vented boilers is that you have access to fresh air as it is important for it to function.

Direct vent boilers are a good option for tightly sealed homes, which is the case nowadays. They take in air from outside the house and let it out, with no chimney at all. It is easy to install in small spaces too as the air is let out by sidewall or ceiling.

  • Efficiency

While we want the warmth, we sure don’t want to pay way too much on it. So, it is important to look through efficiency ratings before you decide on a boiler. The efficiency is calculated by estimating the fuel required by the boiler to convert it into heat that can be later used. This also helps in understanding the cost that the user would have to pay for that.  

Regular users should never go for a boiler that offers them anything beyond a 90% efficiency rating. These boilers make use of aluminum or stainless-steel heat exchangers for producing heat so that you get maximum efficiency and also work for a long period.

For boilers with 80-89% efficiency ratings, while they are cheap and work well in the meantime, they only increase cost in the long run. They use cast-iron heat exchange which is not the most efficient way to get the heat.

While high-efficiency will incur you more cost when you purchase it, it will also help in cutting other costs such as fuel bill and other repairs that low-efficiency boilers might require from time to time.

  • Size

Combi boilers are compact in size, so it is suitable for all house sizes. But for other boilers, you do need to consider house size as it is an important factor in heat distribution throughout the house. A professional will advise you better on these things.

  • Climate

           Cold countries require a central heating system more than anything. Their houses have it in-built as you can’t survive the cold without that. However, for moderate countries, a boiler is only a need during winters. So, choose accordingly while purchasing a boiler. Regular users should invest in a good quality boiler that will last long while other users can get one that’ll help them get through the cold weather with ease.

  • Family size

If there are several people using boilers at once, it is going to directly affect the water pressure. Hence, it is important to consider the size of your family before deciding on a boiler combi boiler are known to be more suitable for smaller family as they provide water directly from the mains, instead of storing it. So, sometimes the water pressure might decline and you may not get your power shower.

What Do Industry Experts Have To Say?

Places with consistent cold weather require boilers immensely. The people survive these extreme climates due to a central heating system, it’s not a choice for them. Since it is a necessity, it is important to be careful about choosing one for their homes. Since it’ll be used on regular basis, the best is to get a good quality one, though it is pricey as it’ll no incur extra cost on repairs in the long run.

Industry experts suggest that it is best to contact an engineer while purchasing a boiler. They will understand your requirements and guide you better about which boiler will be suitable for your household. It is important because different people have different boiler needs in terms of their capacity and other features, so it is best to have an expert inspection done.

However, there is certain general advice that the people looking for boilers can follow in general. Mostly boilers are purchased depending on the house type and the user’s requirement. Small houses don’t need boilers that give output beyond 24-27kW. Medium houses, on the other hand, have more than one bathroom, etc., so a boiler within the range of 28-34kW would do them good. However, if you are residing in a big household that has several members, it would be best if you select a boiler that provides an output of 35-42kW.

Although, there is a suggestion that we would like to give. While combi boilers are extremely efficient and work well as a central heating system, it is mostly suitable for houses with fewer washrooms. The water is supplied from the mains and that might lower the overall water pressure that you would otherwise get from a boiler. However, this is a good thing as it ensures that the water is fresh and safe to use.

Also, now people don’t have to worry too much about getting a budget-friendly boiler for small spaces. The Combi boiler is compact and has just one body that needs to be fit in. Even that can be easily fit in anywhere you want.

Excellent and efficient service from Alpha engineer Mark

Purchased the Alpha boiler service and breakdown cover which was very well priced. Engineer Mark serviced the boiler at the end of last year and noticed the pressure was dropping and advised me to monitor the pressure. As it was still losing pressure I phoned Alpha yesterday and Mark came back and repaired the boiler first thing this morning! What a service! All the Alpha team was excellent on the phone and Mark was very professional.
