Hot water that lasts — energy‑efficient, safe and tailored to your home

A hot water heater should just “work” in everyday life — until it doesn’t. Then you notice it right away: the shower turns lukewarm, the hot water runs out too fast, it drips from the safety valve, or it starts making noise. We help you choose the right solution, replace an old heater and make sure the installation is safe, tight and service‑friendly.

The most important thing is correct sizing for your household and usage. A unit that’s too small leads to constant hot‑water issues, while an oversized one can mean unnecessary energy costs. We look at how many people are in the household, how you use hot water (bath/shower, laundry, dishes) and the conditions where the heater will be installed.

During replacement we check connections, shut‑offs and drain/relief handling — and make sure safety functions like mixing valve and safety valve work as they should. We also consider placement and access so future service is easy and to reduce moisture risk around the installation.

Having issues with hot water, pressure swings or suspect a leak? We can troubleshoot and give a clear recommendation: repair, service or replacement — with a focus on a solution that lasts.

We help homeowners and businesses across the Falkenberg municipality and are based in Ätran. Feel free to send a photo of the current installation and roughly how many people are in the household, and we can quickly guide you to the right choice.

Common questions about hot water heaters

How do I know if my hot water heater needs to be replaced?

Clear signs are that hot water runs out faster than before, the temperature varies, or you hear new noises (clicking, boiling/gurgling). That can indicate buildup, wear or that the heater is working inefficiently.

Dripping or running from the safety valve can sometimes be normal during heating, but if it’s heavy or constant you need to check pressure, valve and installation. Drips that land in the wrong place can cause moisture damage over time.

Rust‑colored water, corrosion around connections, or moisture on/under the heater are warning signs. Then you should act quickly — both to avoid water damage and to prevent sudden failure.

We assess on site and can often say whether it’s worth repairing or if replacement is more economical.

What size hot water heater do I need?

It depends on how many people you are and how you use hot water. A household with multiple morning showers, a bathtub and lots of laundry/dishes has very different needs than a smaller household with more even usage.

It’s not just “liters” that matter, but also recovery speed and temperature settings. In some homes it’s smarter to choose a unit with good recovery rather than simply the largest tank.

We help you size it correctly so you get enough hot water — without paying for unnecessary energy use.

If you want: tell us how many you are, whether you have a bathtub, and if you often shower at the same time — then we can quickly narrow down a reasonable size.

Why does the safety valve drip?

The safety valve can drip when water heats up, because volume expands and pressure must be released. A small amount of dripping during heating can therefore be normal.

But if it drips a lot, often or constantly, it can indicate high water pressure, a worn valve or that expansion isn’t handled correctly. That risks both water waste and moisture damage, especially if the discharge isn’t routed properly.

It’s also important that the valve doesn’t stick. If it doesn’t work properly it can be a safety risk. That’s why it’s wise to have a professional check it if you’re unsure.

We review the whole setup: pressure, valve, discharge and installation design.

My water heater makes noise — is it dangerous?

Noise can come from several things. Clicking and “crackling” can be from temperature changes in the tank and pipes, which is often harmless. A more bubbling or boiling sound can indicate buildup (scale/sediment) that makes the heating element work less efficiently.

When buildup accumulates, heating becomes less efficient and the heater can use more energy. It can also shorten lifespan because components work harder.

Noise can also come from pressure swings or valves that aren’t healthy. Sometimes it’s a simple fix; sometimes it’s a sign it’s time to service or replace the unit.

We can troubleshoot and give a clear recommendation so you don’t have to guess.

Can you replace a hot water heater even if it’s in a tight space?

Often yes. Many heaters are in small spaces, utility closets or areas that are hard to access. The key is that the work can be done safely, connections remain accessible, and the installation is service‑friendly afterward.

In tight spaces we plan extra carefully: how the unit is removed/installed, how to protect surrounding surfaces, and which fittings are needed for a stable solution.

We also look at discharge and drainage. If the heater stands where moisture could be an issue, we review how to reduce risk.

Send a photo of the location and the space dimensions, and we can quickly say what’s possible.

Do I need a mixing valve (temperature limiter)?

In many installations a mixing valve is a good idea, especially if the heater runs at a higher temperature for hygiene and efficiency. The valve mixes down the temperature at outlets to reduce scald risk.

It also provides more consistent shower and tap comfort because temperature is more stable. This is especially relevant in homes with children.

At the same time it has to be set correctly: a mis‑set or worn valve can give uneven temperature or make hot water “run out” faster than it should.

We review what fits your installation and make sure everything works as it should.

Can you troubleshoot if hot water suddenly turns cold?

Yes. When hot water suddenly disappears it could be anything from power/thermostat and heating element to fuse, overheat protection or settings. Sometimes it’s a simple reset; sometimes it’s a clear sign of wear.

We troubleshoot systematically: we check function, temperature, components and how the heater behaves during operation. That gives us a clear action plan.

If the heater is older we can also help you compare: is it worth repairing or is replacement better? We weigh both cost and risk of future issues.

The goal is a stable solution — not just “warm again for now.”

How can I reduce energy use for hot water?

First it’s about correct sizing. A unit that’s too large can mean you heat more water than you need, while one that’s too small often leads to heavy load and inefficient operation.

Temperature settings also matter. Too low can create hygiene issues, too high can cause unnecessary losses. With the right settings and a working mixing valve, you get both safety and comfort.

Insulation and pipe routing can also matter. Long pipe runs without good insulation lose heat along the way, which shows up in both time and energy cost.

We can give concrete advice based on your system and how you use hot water day to day.

How long does a hot water heater replacement take?

It depends on access, existing connections and whether anything needs to be updated (for example valves, discharge routing or fittings). In many cases it goes smoothly, but in older installations there may be worn parts that should be replaced for a safe overall setup.

We spend time making it service‑friendly and safe. An installation that is “quickly done” but hard to maintain or that drips later is never a win.

When we can see photos of the existing installation, we can often tell right away whether it looks like a simple swap or requires more planning.

The most important thing is that you get an installation that lasts, not just one that gets connected.

What do you need to know when I want a quote or to book?

Tell us roughly how many people are in the household, whether you have a bathtub, and if you feel hot water runs out. Also mention if the heater is in a tight space and if you know the approximate size or model of the old unit.

Please send a photo of the heater and the connections around it (water in/out, valves and any discharge). That helps us bring the right materials and plan the job efficiently.

If you have symptoms — dripping, noise, uneven temperature — note when it happens and how often. That makes troubleshooting easier if needed.

With good input we can often give a clear recommendation quickly: repair, service or replacement — with the right size and setup.
