Replace your kitchen water heater / water heater / central heating boiler with an electric (continuous flow) boiler
Perfect for apartments, apartment buildings, studios, and renovations without a (safe) flue. This guide explains everything: safety, power, options, costs, and local coverage.
Why people choose an electric boiler or instantaneous water heater
1) Safety
No combustion = no carbon monoxide risk. No flue gas exhaust is required, so no draft or detection issues.
2) Space & simplicity
Compact, quiet, and low-maintenance. Fits in a kitchen cupboard, meter box, or shaft. Flue gas renovation is no longer necessary.
3) All-electric ready
Join the sustainability movement. Combine smartly with solar panels or dynamic electricity rates.
The risks of gas-fired appliances (especially in apartments)
- Outdated flue gas exhausts: communal ducts in apartment buildings are often outdated or prohibitively expensive to renovate. Cracks/leaks or improper materials = CO hazard .
- Limited ventilation: Kitchen heaters in small spaces can be dangerous if there is insufficient ventilation.
- CO poisoning: Incomplete combustion or a faulty exhaust system is a real risk. CO is odorless and deadly.
- Maintenance & inspection: Gas requires periodic maintenance and CO measurement; deferred maintenance increases the risk.
- Homeowners' Association (VvE) regulations: Replacement often falters due to flue gas requirements, shaft capacity, or collective costs. All-electric bypasses this.
Conclusion: where the flue gas exhaust cannot be replaced (affordably), an electric (continuous flow) boiler or heat pump boiler is the safest and often most cost-effective route.
Which electric option suits your situation?
| Option | How does it work | Plus points | Points of interest | Typical applications |
|---|---|---|---|---|
| Electric instantaneous water heater (instant) | Heats water on demand without a storage tank. | No downtime losses, super compact, “endless” hot water within the power limit. | For shower comfort, 3-phase (18–24 kW) is often required; flow/temperature depends on kW and inlet temperature. | Kitchen/sink, compact showers, lounges, company kitchens. |
| Electric storage boiler (10–200 L) | Keeps a barrel of water at the right temperature, instantly available. | Often 1-phase (10–16 A), stable comfort, easy installation. | Small downtime losses; smart control (night current/PV) pays off. | Kitchen 10–15 L; bathroom 80–150 L; family apartments. |
| Heat pump boiler | Extracts heat from ambient air; 2–3× more efficient (COP). | Low consumption, often ISDE subsidy, ideal with PV. | Larger device; space/ducts required. | Apartments with storage space/technical cupboard, VvE projects. |
Quick selection (rule of thumb)
- Kitchen : 10–15 L kitchen boiler or 9–12 kW continuous flow (one tap).
- Shower (one at a time): 50–100 L boiler or 18–24 kW flow (3-phase + correct shower head).
- Entire apartment : 80–150 L (electric) or heat pump boiler 200–300 L.
Power, distribution box and connection
1-phase solutions
Most storage boilers up to approximately 2 kW operate on 230V/10–16A. They often require no grid reinforcement. Energy consumption can be intelligently controlled with a timer or PV system.
3-phase flow
For comfortable shower flow rates, 3x25A is often required (18–24 kW unit). We'll check your mains connection and arrange for reinforcement and protection where necessary.
Tip: Water-saving shower head (7–9 l/min) improves comfort at lower power.
Costs, consumption and savings
- Installation: often cheaper than flue gas renovation for gas geysers/central heating boilers.
- Consumption: flow = no standstill loss; boiler = small loss but cheap to control (night/PV).
- Maintenance: no burner or flue gas parts ⇒ less maintenance .
- Subsidy: heat pump boilers are often eligible for ISDE.
The exact price depends on the connection, plumbing, and desired comfort level. We'll clarify this during the consultation.
Step-by-step plan: how we replace your geyser/central heating boiler
- Inventory: photos/situation, desired comfort (kitchen/shower), current connection (1-phase/3-phase).
- Advice & choice: continuous-flow, (storage) boiler or heat pump boiler + accessories.
- All-in quote: including installation, commissioning and necessary security measures.
- Installation: dismantling of old device, installation of new device, testing and explanation of use.
- Aftercare: maintenance advice and optimization (timer/PV/dynamic tariff) if necessary.
Frequently Asked Questions
Is an electric boiler safe in an apartment?
Yes. There's no combustion, so no carbon monoxide or flue gas exhaust is required. We install according to standards, with the correct (leakage) current and earth leakage protection.
Do I need 3-phase?
Not for most storage water heaters. Usually, yes for shower instantaneous water heaters (18–24 kW at 3x25A). We'll assess your situation and provide you with honest advice.
Can I leave my old flue in place?
With all-electric hot water systems, a flue gas exhaust is no longer necessary. Homeowners' associations often avoid the significant renovation costs of communal ducts.
What is better: a continuous-flow or a (heat pump) boiler?
Continuous flow is compact and efficient for on-demand use, but often requires a 3-phase power supply. A (heat pump) boiler uses storage, is peak-friendly, and (with WPB) very economical.
