Why is ratiotherm technology worth it?
Conventional boiler technology:
Investment: 1.740,- €
Hot water tank (boiler) 400 L
- with cleaning opening
- Heating circulating pump (tank charging pump)
- Pump stop set return set
- Charge and discharge line with insulation
ratiotherm fresh water system:
Investment: 2.440,- €
- with stratified storage tank with 400 litre volume
- Ball valve set
- Direct attachment kit
- Support rail
- Compact domestic water station
- Heating water circulating pump
- and tank charging pump
Additional consumption boiler technology:
Additional consumption in boiler system due to:
- Heat loss due to higher supply temperature (65 °C)
- Cooling loss due to connections in the hot zone
- Inefficiency of the condensing boiler technology due to high return temperatures and great losses in the circulation
Savings with fresh water technology
- Supply temperature (55 °C)
- No connections in the hot zone (therefore no heat loss)
The result:
Purely in figures:
- Additional investment of €700 for fresh water technology
- Savings with an oil price of €0.40/litre:
- Boiler: 340 l/year x €0.40/litre = €136/year
- OSKAR: 430 l/year x €0.40/litre = €172/year
Amortisation at the same oil price - 4 to 5 years
Advantages of ratiotherm fresh hot water technology:
- less calcification and
- less maintenance for fresh water systems
- Solar compatibility of the system both
- for hot water and
- heating support
- for hot water and
- Hygienic, healthy, domestic hot water
- High hot water output
- Ability to accommodate requirements
