A guide to Viessmann boilers for Dublin

Your boiler is one of the most important appliances in a modern home. We rely on it to keep our families warm and comfortable, regardless of what the weather is doing outside. Being without heat and hot water for even a short period of time would be awful. Thankfully, modern boilers are extremely reliable. However, regular servicing and the recommended maintenance will substantially reduce the likelihood of a breakdown even further.

In this post we’ll try to answer all the main questions about the installation, maintenance, and costs of choosing a Viessmann boiler in Dublin.

About Viessmann boilers

Viessmann is a long established and trusted brand. Established in 1917 and serving more than 11 countries, Viessmann is well known in most developed markets. The range of boilers they offer is designed to ensure they have a solution for any size or type of home. Each type of boiler is also available with a range of heat outputs and water flows, increasing the suitability for specific homes further. They manufacture combi-boilers, system boilers, heat-only boilers and storage combis.

The importance of maintenance

The importance of properly maintaining your Viessmann boiler can’t be overstated. An annual check by a qualified and experienced professional, regardless of the age of your boiler, not only greatly reduces the likelihood of a breakdown, but it also helps to keep your family safe by making sure everything is working properly. Some people just have a gas safety inspection, while others will just have a service. To ensure your boiler remains efficient and safe, both are recommended. They can usually be performed at the same time, keeping the cost and inconvenience to a minimum.

There is a crossover between the requirements of a service and safety inspection, so the time saving can be considerable. The engineer will normally check your air supplies, flues, boiler, and any associated safety devices or equipment are all working as they should be.

If you have a newer boiler that is still under warranty, then sticking to the service and inspection schedule will ensure you remain covered by the manufacturer’s warranty.

A Viessman boiler in Dublin can save you money

A new Viessmann boiler in Dublin can save you money in more ways than one. As well as modern boilers being much more efficient, reducing your utility bills, they are also far less likely to generate any repair bills. The savings can be even greater if your current boiler isn’t the correct size or type for your home. If you have a boiler that is ten or more years old, then the savings can easily be in the hundreds of euros every year.

The types of boilers available

There are different types of boilers available. Viessmann boilers in Dublin can provide combi boilers, conventional boilers, or system boilers. Choosing the right type and system for your home can make a huge difference. Below we’ll list some of their main characteristics to help you better understand your choices.

Combi boilers

Combi boilers are the most popular choice in modern homes. With a combi boiler water is heated straight from the mains and delivered at pressure, removing the need for separate pumps or power showers. A combi boiler often takes up less space, as it removes the need for a hot water cylinder. The lack of a tank can also cut the cost of installation. Because the water is heated on demand it can take a few seconds before the water gets warm, and the pressure can reduce if several people are using taps in different parts of the house at the same time.

Conventional boilers

Conventional boilers can be more effective in a home with lots of bathrooms and heavy use. This type of system can be overkill for smaller homes and take up more space. They are typically found in older properties. They can send hot water to multiple rooms with no loss in pressure, and many systems also have an immersion heater as a backup, so you can still have hot water even if the boiler breaks down. A conventional boiler does require a little more planning, as water isn’t heated instantly you’ll have to program your thermostat to ensure the water is always preheated when it will be needed. If all the hot water in the tank is used before you’re finished, you’ll have to wait for more water to be heated. Most older properties have their hot water cylinder and cold-water tank in the lofts, but space can be an issue on some properties.

System boilers

A system boiler can be a great option for household that consume a lot of hot water. They work in a similar way to a combi boiler but also feature a storage cylinder. They are most commonly found in large family homes or B&Bs etc. Multiple taps can be used without any loss in pressure. The compact size makes them an ideal choice for people with space issues, and installation is often quicker and easier. However, while they are relatively compact, they are bigger than a traditional boiler because of the internal water tank.

Are you the landlord of a property that needs a boiler check?

It doesn’t matter if the property you rent out is a commercial or a domestic one, you have legal responsibilities to ensure it’s safe for your tenants. It has to be free from damp, in good structural repair, have hot and cold running water, it needs adequate means of heating and ventilation and the electrics and gas need to be in a good state of repair.

The importance of a boiler check

If your rented property looks as though it has been cared for, your tenants are more likely to treat it with the respect it deserves. However, there are more important things to think about, as safety should be your number one priority.

Before anyone moves into your property you should have all the electrics checked to ensure they are in good working order and not likely to break down or cause a fire.

When it comes to the gas in your property, if this is faulty, the tenants could be made ill, or even worse, a fault could be fatal for them. It’s for this reason that all landlords have to arrange a boiler check and service each year and need a certificate to prove it has been done.

A boiler check can only be carried out by a Registered Gas Installer and it’s illegal for anyone else to carry out any required work. The possibility of carbon monoxide poisoning, which is colourless, odourless and tasteless means that only qualified engineers should be dealing with any gas in your property. Large quantities of this gas, which is often referred to as the silent killer, can accumulate if there are blockages, poor ventilation or a fault on an appliance.

Having your boiler check completed by experienced experts is vital for your peace of mind knowing that your tenants are safe.

At the same time as carrying out your boiler check, a qualified engineer will be able to let you know if any of your heating system or other appliances need replacing. This is sometimes the best thing to do, especially when you consider the older equipment gets the more costly it becomes to run.

At GasSafe Engineering we are able to complete your boiler check and assist you with all areas of your heating needs. From servicing to repairs, replacements and new installations, our engineers have the qualifications and experience to deal with them all.

Energy performance certificates

The better your Energy Performance Certificate (EPC) is the more attractive your property will be to prospective tenants. The energy assessors use government approved software to establish how energy efficient your property is. There are several things that are considered, the heating system and other appliances among them. It looks at the type of construction, if there is double glazing and the efficiency of your gas and electric. If you are arranging for your EPC it is a good idea to have a boiler check before the assessor visits.

No one should think of the certification as a comment on the condition of the property, but a good energy rating is great if you want to rent your premises to someone else.

Your other obligations as a landlord in Dublin

You will have legal duties other than arranging a boiler check and ensuring the electrics are safe. You also have to:

  • Not charge rent of more than the market value of the property
  • Provide your tenant with a rent book or a statement of rent paid
  • You must register residential properties with the Private Residential Tenancies Board (PRTB). This involves registering the details of the tenancy using a form that can be downloaded. You also have to say how many bedrooms there are, how many people will be living in the property and provide all the names and details of any agent acting for you. The form also asks the date the tenancy started, how much the rent will be and how often it has to be paid. The form has to be signed by yourself and the tenants. Failure to register can result in a fine of up to 3000 euros plus 250 euros per day if you still fail to fulfil your obligations.
  • You should try to give them 90 days’ notice of any increase in the rent, but at least a minimum of 28 days
  • Keep the structure of the property in a good state of repair
  • Maintain the interior of the property to the standard it was at the start of the tenancy
  • Repay the tenant for any bills they have to cover for repairs that should have been carried out by you
  • Give the tenant all the information they need if someone else, such as an agent, will be acting on your behalf
  • Return any deposit they paid when the leave the property unless there is unpaid rent, or they have caused damage.
  • Give them a valid notice of termination when you want them to leave

Tenants have obligations too and it is wise to ensure they are aware of them or complaints can be made to the PRTB. Residential tenants should be allowed to live in peace and commercial tenants should be allowed to run their business without interference.

Is it worth it?

All these legal duties may make you wonder if it’s worth investing in property and becoming a landlord. It’s not as daunting as it sounds, which is why there are so many private landlords in Dublin and the rest of Ireland.
