Hot water is one of the fundamental needs guests expect to be met in any hotel or apartment. However, for many small and medium hospitality owners, ensuring stable hot water supply becomes a constant source of stress, especially at peak season. Solving this problem can significantly boost your rating and protect your reputation.
The hot water problem every mini-hotel owner faces
Imagine a typical scenario: 7:30 am, your mini-hotel is 80% occupied. The first guests take showers — the water is hot and everyone is happy. But after 15 minutes the first complaint appears in the chat: "Our water is barely warm, it’s impossible to shower!" Then comes the second, the third... The phone won’t stop ringing, and a negative review on Booking is already posted. You rush to the boiler — it’s running at full power, but it simply can’t heat enough water for everyone.
Why a hot water shortage happens for guests:
- A typical gas or electric boiler is designed for sequential use, not 5–10 showers at the same time
- An “oversized” 300–500 L tank runs out in 20–30 minutes under heavy use
- Reheating the next batch takes 2–4 hours — guests won’t wait that long
- In summer heat, traditional boilers perform worse due to overheating and reduced efficiency
- Owners pay huge gas/electricity bills, yet service quality remains low
Business impact
The DHW problem in rental apartments or mini-hotels has serious consequences:
- Negative reviews on Booking and Airbnb (ratings drop, fewer bookings)
- Loss of guest loyalty (they won’t return or recommend you)
- Constant stress and emergencies during the season when you should be making profit
- The need to install multiple boilers, leading to extra costs and taking up space
- Inability to scale the business (bought the neighboring villa — faced the same problem again)
- For remote locations by a river, in the forest or mountains, the situation is worsened by the lack of a gas main, forcing expensive electric heating
Real quotes from owners
Here’s what owners say who faced hot water problems at their properties:
- "Every morning I pray not all guests go to shower at the same time"
- "We had to set a shower schedule — that’s absurd in 2025"
- "We lost 20% of bookings due to a single string of negative reviews about water"
- "There’s no gas at our mountain villa, the electric boiler eats huge sums every summer"
Why a heat pump is the best DHW solution in summer
How MBasic solves the efficiency problem
The Mycond MBasic air-to-water heat pump fundamentally changes the hot water situation in mini-hotels and apartments:
- Air-to-water principle: the heat pump doesn’t “create” heat from electricity (like a boiler), it “moves” it from ambient air
- In summer the COP reaches an impressive 5–6: from 1 kW of electricity you get 5–6 kW of thermal energy (5–6 times more efficient than an electric boiler!)
- For comparison: in winter COP = 3–4, and in summer at +25–35°C — 5–6 (25–50% higher)
- Specific example: heating 500 L of water to 55°C:
- Electric boiler: consumes 30 kWh of electricity
- MBasic in summer: consumes only 5–6 kWh (5 times less!)
- The hotter it is outside, the more efficient the heat pump works (your benefit is maximal right at peak season)
- The MBasic monobloc operates up to +43°C outdoor temperature — no limitations for hot regions
A solution for remote locations without gas
For business owners whose properties are located remotely, a heat pump for an eco-lodge or a heat pump for a holiday base becomes the optimal solution:
- Eco-lodges in forests, villas in the mountains, river resorts — often have no access to a gas main
- An electric boiler “eats” up to 70–80% of the property’s total electricity
- MBasic reduces this to 15–20% thanks to its high COP
- Can operate from a standard 230 V supply (no 380 V three-phase needed)
How to ensure DHW stability during peak loads
Why MBasic handles peak loads
The secret to reliable hot water supply in hotels and apartments lies in proper system selection:
- The secret is the combination of a heat pump + a properly sized storage tank
- The heat pump continuously maintains the tank temperature (doesn’t wait for depletion like a traditional boiler)
- The inverter heat pump smoothly modulates power depending on demand
- Even if the tank is partly depleted, reheating is 3–4 times faster than with an electric boiler
Checklist for sizing a heat pump for a mini-hotel
To correctly size a heat pump for your property, consider the following:
- Number of rooms/apartments
- Average summer occupancy (60–80–100%)
- DHW consumption per guest: 80–120 L/day
- Peak hours (simultaneous shower use): typically 7–9 am, 7–9 pm
- Presence of a pool/jacuzzi/spa (additional load)
- Supply temperature for DHW: 50–55°C
- Storage tank volume (safety factor 1.3–1.5)
Sizing formula for apartments: P_dhw = (number of guests × 100 L × ΔT°) / (860 × heating time)
Sizing examples for different property types
- Apartments by the sea/river: 5 apartments (4 guests each) → 20 people → need 2000 L/day → MHM-U06HL (7.2 kW) + 300–500 L tank
- Mini-hotel on the coast/in the mountains: 10 rooms (20 guests) → need 2000 L/day → MHM-U09HL (9.7 kW) + 500 L tank
- Large villa/eco-lodge: 15 rooms (30 guests) → need 3000 L/day → MHM-U12HL (11.9 kW) + 750–1000 L tank
- Holiday base with a pool: 12 rooms + pool → MHM-U12HL + 1000 L tank + separate pool circuit

Comparison with alternative solutions
To make an informed decision, it’s important to compare different hot water options for hotels:
Gas boiler
- Advantages: lower initial cost, fast heating of large volumes
- Disadvantages: requires a gas main (not available in forest/mountain locations), high operating costs in summer (low efficiency in heat), no cooling function, dependency on gas supply
- Best when: cheap mains gas is available, large hotel (>30 rooms), year-round operation with high load
Electric boiler
- Advantages: simplest installation, low initial cost
- Disadvantages: most expensive to run (COP=1 versus 4–6 with a heat pump), grid overload, slow reheating during peak loads
- Best when: very small property (1–2 apartments), occasional use, very limited starting budget
Solar thermal collectors
- Advantages: minimal operating costs, eco-friendly
- Disadvantages: weather-dependent (cloudy days are an issue), requires backup heating, high initial cost, takes a lot of roof space
- Best when: hybrid system (solar + MBasic as backup), very sunny region, long-term project

Frequently asked questions about heat pumps for DHW
Is MBasic enough for 10 rooms/5 apartments in summer at full occupancy?
Yes, the MHM-U09HL (9.7 kW) or MHM-U12HL (11.9 kW) + a 500–750 L storage tank will fully cover needs even during morning/evening peaks. The inverter compressor automatically increases power as demand grows.
How much do I save compared to a gas/electric boiler in summer?
In summer, savings reach 50–70% versus an electric boiler (thanks to a COP of 5–6). Compared to a gas boiler — it depends on local tariffs, but typically 30–50% savings on DHW.
Does the heat pump cope during peak loads when all guests shower at once?
Yes, if the storage tank is properly sized (safety factor 1.3–1.5). The heat pump continuously maintains the tank temperature rather than waiting for full depletion. Even under intensive use the water doesn’t cool critically.
Can MBasic be used for a pool/jacuzzi on site?
Yes, via a dedicated plate heat exchanger or a separate hydraulic circuit. One unit can serve both DHW for rooms and pool heating (depending on capacity).
