Solar Surplus for Heating and Hot Water

Im Hüdel, Neftenbach
ASKOHEAT heating element and control unit for electric heat generation in Neftenbach
Project Description

Adding solar electricity to an existing log-heating system

At Im Hüdel in Neftenbach, our PV partner installed a photovoltaic system with SWO / SwissWatt One solar panels, a Sigenergy inverter and battery storage. We added an extended energy management system. When the photovoltaic installation produces more electricity than the house and battery can absorb, the remaining surplus is used to generate heat. We integrated the large heating-water storage system already serving the existing log boiler. This allows solar electricity to be stored as heat and used to warm the house. The existing log boiler remains part of the installation.

Project Description

Managing heating-water storage and hot water with Loxone

We use ASKOHEAT heating elements to generate heat electrically. An ASKOWALL unit with an integrated circulation pump connects this heat source to the heating system. The domestic hot-water cylinder is also heated electrically. Energy management runs on Loxone, with the connected systems communicating over Modbus TCP. This brings photovoltaics, battery storage and the existing heating equipment together so that additional solar surplus can be used for heating and hot water.

Renovated bathroom at Gütschstrasse in Binz with bath, washbasin and gold- and bronze-toned fittings

An Elegant Bathroom with a Recessed Mirror Cabinet

High-quality wall and floor finishes, gold- and bronze-toned fittings and a continuous service wall: At Gütschstrasse, we integrated a concealed cistern and recessed mirror cabinet and coordinated the renovation with the tiler.

Outdoor air-conditioning unit on the facade at Im Hüdel in Neftenbach

Multisplit Air Conditioning with Loxone Control

Four air-conditioning units in a multisplit installation: Loxone controls each indoor unit according to room temperature. Central app control provides cooling in summer and heating during the transitional seasons.

A Thoughtful Bathroom Renovation in Binz

Preserving existing finishes while carefully updating the bathroom: At Gütschstrasse, we matched new tiles to the retained surfaces, corrected the wall construction and coordinated the entire renovation.

PV and PVT rooftop installation at Chürzistrasse in Dübendorf

Heat Pump, PVT and Battery Working Together

A 75 kW gas heating system replaced by a 42 kW heat pump with water-filled borehole heat exchangers: PVT, 25 kWp of photovoltaics, a 55 kWh battery and Loxone connect heating, cooling and electricity for tenants. Planned and installed by our own team.

Concealed air-conditioning system with two discreet air outlets in a sloping roof

Cooling Technology Where Standard Doesn't Fit

Three properties, three unusual installation situations: a unit without a suitable rear wall, a recessed ceiling cassette and a concealed installation in a sloping roof. We planned each solution individually and coordinated all other trades involved.

New NIBE heat pump installed on a small plinth in a plant room in Zumikon

Heating, Hot Water and Cooling in a Tight Space

In Zumikon, we replaced the existing heat pump with the appropriate NIBE successor model. The new unit had to continue providing heating, domestic hot water and cooling from a very small plinth – and we also brought the faulty wine-cooling unit back into operation.

Air-to-water heat pump on the roof of an apartment building in Bassersdorf

Heat Pump Repaired, Existing System Retained

In an eight-apartment building in Bassersdorf, the heat pump failed after compressor damage. Targeted repairs and hydronic improvements allowed the existing system to remain in use.

Air-to-water heat pump in a family home on Lägernstrasse in Dübendorf

Family Home Heating Replacement with a Heat Pump

In a typical family-home neighbourhood in Dübendorf, we replace existing oil and gas heating systems with properly sized air-to-water heat pumps and coordinate the entire project.

Twin pellet boiler system with two ETA ePE-K 240 boilers in Uster

When a Heat Pump Won't Do: 480 kW from Pellets

For a listed property with annual gas consumption of around 1 million kWh, our feasibility study led to a 480 kW twin-boiler pellet heating system.

Hydraulic schematic of the new heat pump system in Zollikon

Heating for House and Pool, Cooling for the Building

At a property in Zollikon, the existing heat pump caused problems with domestic hot water, pool heating and free cooling. A new ground-source heat pump and redesigned hydronics allow these functions to operate simultaneously.

Eight Heat Pumps on One Shared Borehole Field

Four semi-detached apartment buildings in Dübendorf relied on an ageing central oil boiler. We installed four decentralised plant rooms with eight ground-source heat pumps sharing a field of 27 boreholes.

750 kW Hoval gas condensing boiler at Industriestrasse in Dietlikon

750 kW of Heating for Two Commercial Buildings

An ageing Viessmann twin oil-boiler system was replaced by a 750 kW Hoval gas condensing boiler. The new control system serves ten heating circuits across two buildings.

Two Buildings, Two Independent Ground-Source Systems

Two apartment buildings in Fällanden shared an oil heating system. Following a feasibility study, we replaced it with two fully independent ground-source heat pump systems, each with its own domestic hot water preparation.

New heating system on MS Helvetia on Lake Zurich

A New Heating System for MS Helvetia

Zürichsee-Schifffahrtsgesellschaft commissioned us to replace the diesel heating system on MS Helvetia. At the same time, we solved the uneven heat distribution on board.

Pellet heating system for the church building in Schwerzenbach

Pellet Heating for a Church and Residential Building

For the new church building in Schwerzenbach, we worked with the specialist planner to install a pellet heating system combining different heat distribution systems and domestic hot water preparation.

75 kW air-to-water heat pump serving two apartment buildings in Gutenswil

75 kW from the Air for Two Apartment Buildings

Two apartment buildings in Gutenswil shared a 75 kW oil boiler, but geothermal boreholes could not be approved. We replaced the oil boiler with a 75 kW air-to-water heat pump for heating and domestic hot water.

Central plant of the private district heating network in Freudwil

A Private District Heating Network for Freudwil

Two Fröling wood-chip boilers with outputs of 150 and 60 kW supply houses and apartment buildings in Freudwil through a private district heating network. We installed the central plant, substations and complete connections for the individual heat consumers.

Completed bathroom renovation at Frickenstrasse in Dübendorf

Bathroom Renovation from a Single Source

For this bathroom renovation in Dübendorf, we handled the complete planning, supply and coordination of the work involved – from product selection to the finished bathroom.

Cascade of two Alpha innoTec air-to-water heat pumps in Brüttisellen

Cooling with Heat Pumps, Saving Gas in Winter

For a commercial property in Brüttisellen, we supplemented the existing gas heating system with two Alpha innoTec air-to-water heat pumps. They provide around 40 kW of cooling in summer and reduce gas consumption in winter.
